We identify two carotenoid triplet state lifetimes of [~]13 and [~]42 {micro}s in the spectral region between 1800 and 1100 cm1 after excitation of the blue' and red' peridinin (Per) conformers and the Qy of chlorophyll-a (Chl-a). The fast and slow decaying triplets exhibit different spectral signatures in the carbonyl region. The fast component generated at all excitation wavelengths is from a major conformer with a lactone stretching mode bleach at 1745 cm1. One (1720 cm1) and two (1720 cm1 and 1741 cm1) different Per conformers are observed for the slow component upon 670- and 530480-nm excitation, respectively. The above result implies that 3Per triplets are formed via two different pathways, corroborating and complementing visible triplet-singlet (T-S) spectra (Kleima et al., Biochemistry (2000), 39, 5184). Surprisingly, all difference spectra show that Per and Chl-a modes are simultaneously present during the 3Per decay, implying significant involvement of 3Chl-a in the 3Per state. We suggest that this Per-Chl-a interaction via a delocalized triplet state lowers the 3Per energy and thus provides a general, photoprotection mechanism for light-harvesting antenna complexes. }, doi = {10.1529/biophysj.107.106674}, eprint = {http://www.biophysj.org/cgi/reprint/93/6/2118.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/93/6/2118} } @ARTICLE{BaffreauJ._jp066415+, author = {Baffreau, J. and Leroy-Lhez, S. and Hudhomme, P. and Groeneveld, M.M. and van Stokkum, I.

In this paper, the pathways of excited-state energy transfer and relaxation in PCP were identified by means of femtosecond visible-pump, mid-infrared probe spectroscopy. In addition, excited-state relaxation of peridinin dissolved in organic solvent (CHCl3 and MeOH) was investigated. For peridinin in solution, the transient IR signatures of the low-lying S-1 and intramolecular charge transfer (ICT) states were similar, in line with a previous ultrafast IR study. In PCP, excitation of the optically allowed S-2 state of peridinin results in ultrafast energy transfer to Chl-a, in competition with internal conversion to low-lying optically forbidden states of peridinin. After vibrational relaxation of the peridinin hot S-1 state in 150 fs, two separate low-lying peridinin singlet excited states are distinguished, assigned to an ICT state and to a slowly transferring, vibrationally relaxed S-1 state. These states exhibit different lactone bleaches, indicating that the ICT and S-1 states localize on distinct peridinins. Energy transfer from the peridinin ICT state to Chl-a constitutes the dominant energy transfer channel and occurs with a time constant of 2 ps. The peridinin S-1 state mainly decays to the ground state through internal conversion, in competition with slow energy transfer to Chl-a. The singlet excited state of Chl-a undergoes intersystem crossing (ISC) to the triplet state on the nanosecond timescale, followed by rapid triplet excitation energy transfer (TEET) from Chl-a to peridinin, whereby no Chl-a triplet is observed but rather a direct rise of the peridinin triplet. The latter contains some Chl-a features due to excitonic coupling of the pigments. The peridinin triplet state shows a lactone bleach mode at 1748 cm(-1), while that of the peridinin ICT state is located at 1745 cm(-1), indicating that the main channels of singlet and triplet energy transfer in PCP proceed through distinct peridinins. Our results are consistent with an energy transfer scheme where the ICT state mainly localizes on Per621/611 and Per623/613, the S1 state on Per622/612 and the triplet state on Per624/614.} } @ARTICLE{biophysj.108.139246, author = {Cosimo Bonetti and Tilo Mathes and Ivo H.

Transient absorption signals indicate a subpicosecond excited-state proton-transfer reaction in the pB state that results in chromophore deprotonation prior to the cis-trans isomerization required in the photorecovery dynamics of the pG state.

Two spectral species were found in the chlorophyll T-S spectra of CP47, which may arise from a difference in ligation of the pigments or from an additional hydrogen bond, similar to what has been found for Chl molecules in a variety of solvents. The T-S spectra show that the lowest lying state in CP47 is at approximately 685 nm and gives rise to fluorescence at 690 nm at 4 K. The fluorescence quantum yield is 0.11 +/- 0.03 at 4 K, the chlorophyll triplet yield is 0.16 +/- 0.03. Carotenoid triplets are formed efficiently at 4 K through triplet transfer from chlorophyll with a yield of 0.15 +/- 0.02. The major decay channel of the lowest excited state in CP47 is internal conversion, with a quantum yield of about 0.58. Increase of the temperature results in a broadening and blue shift of the spectra due to the equilibration of the excitation over the antenna pigments. Upon increasing the temperature, a decrease of the fluorescence and triplet yields is observed to, at 270 K, a value of about 55% of the low temperature value. This decrease is significantly larger than of chlorophyll a in Triton X-100. Although the coupling to low-frequency phonon or vibration modes of the pigments is probably intermediate in CP47, the temperature dependence of the triplet and fluorescence quantum yield can be modeled using the energy gap law in the strong coupling limit of Englman and Jortner (1970. J. Mol. Phys. 18:145-164) for non-radiative decays. This yields for CP47 an average frequency of the promoting/accepting modes of 350 cm-1 with an activation energy of 650 cm-1 for internal conversion and activationless intersystem crossing to the triplet state through a promoting mode with a frequency of 180 cm-1. For chlorophyll a in Triton X-100 the average frequency of the promoting modes for non-radiative decay is very similar, but the activation energy (300 cm-1) is significantly smaller. }, eprint = {http://www.biophysj.org/cgi/reprint/68/1/281.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/68/1/281} } @ARTICLE{i99a, author = {Groot, M-L and Frese, RN and de Weerd, FL and Bromek, K and Pettersson {\AA} and Peterman, EJG and van Stokkum, I.

Both time-gated spectra and single wavelength traces were measured. Global analysis of the data established that in the time domain between 5 ns and 2 s only two intermediates are involved in the room temperature photocycle of PYP, as has been proposed before (Meyer T.E., E. Yakali, M. A. Cusanovich, and G. Tollin. 1987. Biochemistry. 26:418-423; Meyer, T. E., G. Tollin, T. P. Causgrove, P. Cheng, and R. E. Blankenship. 1991. Biophys. J. 59:988-991). The first, red-shifted intermediate decays biexponentially (60% with tau = 0.25 ms and 40% with tau = 1.2 ms) to a blue-shifted intermediate. The last step of the photocycle is the biexponential (93% with tau = 0.15 s and 7% with tau = 2.0 s) recovery to the ground state of the protein. Reconstruction of the absolute spectra of these photointermediates yielded absorbance maxima of about 465 and 355 nm for the red- and blue-shifted intermediate with an epsilon max at about 50% and 40% relative to the epsilon max of the ground state. The quantitative analysis of the photocycle in PYP described here paves the way to a detailed biophysical analysis of the processes occurring in this photoreceptor molecule. }, eprint = {http://www.biophysj.org/cgi/reprint/67/4/1691.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/67/4/1691} } @ARTICLE{Hoff1997, author = {Hoff, Wouter D. and Van Stokkum, Ivo H.

The folding and unfolding processes were triggered by an ultrafast laser pulse that isomerized the cross linker within a few picoseconds. The main folding and unfolding times (700 ns and 150 ns, respectively, at room temperature) are in line with previous T-jump experiments obtained from similar peptides. However, both processes show complex, strongly temperature-dependent spectral kinetics that deviate clearly from a single-exponential behavior. Whereas in the unfolding experiment the ensemble starts from a well defined folded state, the starting ensemble in the folding experiment is more heterogeneous, which leads to distinctly different kinetics of the experiments, because they are sensitive to different regions of the energy surface. A qualitative agreement with the experimental data-set can be obtained by a model where the unfolded states act as a hub connected to several separated "misfolded" states with a distribution of rates. We conclude that a rather large spread of rates (k1 : kn {approx} 9) is needed to explain the experimentally observed stretched exponential response with stretching factor {$\beta$} = 0.8 at 279 K. }, doi = {10.1073/pnas.0607748104}, eprint = {http://www.pnas.org/cgi/reprint/104/13/5383.pdf}, url = {http://www.pnas.org/cgi/content/abstract/104/13/5383} } @ARTICLE{JanneA.Ihalainen10012002, author = {Ihalainen, Janne A. and Jensen, Poul Erik and Haldrup, Anna and van Stokkum, Ivo H.

For this purpose, the protein was labeled at seven key positions. This places the label at well-defined locations from the water phase to the center of the hydrophobic acyl chain region of a phospholipid model membrane, providing us with a nanoscale ruler to map membranes. Analysis of the time-resolved fluorescence spectroscopic data provides the characteristic time constant for the twisting motion of the BADAN label, which is sensitive to the local flexibility of the protein-lipid environment. In addition, we obtain information about the mobility of water molecules at the membrane-water interface. The results provide an unprecedented nanoscale profiling of the dynamics and distribution of water in membrane systems. This information gives clear evidence that the actual barrier of membranes for ions and aqueous solvents is located at the region of carbonyl groups of the acyl chains.} } @ARTICLE{RemcoKort07012005, author = {Kort, Remco and O'Brien, Andrea C. and van Stokkum, Ivo H.

Wild-type RCs both with and without the quinone electron acceptor QA, were excited at 600 nm (nonselective excitation), 800 nm (direct excitation of the monomeric bacteriochlorophyll (BChl) cofactors), and 860 nm (direct excitation of the dimer of primary donor (P) BChls (PL/PM)). The region between 1600 and 1800 cm-1 encompasses absorption changes associated with carbonyl (C=O) stretch vibrational modes of the cofactors and protein. After photoexcitation of the RC the primary electron donor P excited singlet state (P*) decayed on a timescale of 3.7 ps to the state [IMG]f1.gif" ALT="Formula" BORDER="0"> (where BL is the accessory BChl electron acceptor). This is the first report of the mid-IR absorption spectrum of [IMG]f2.gif" ALT="Formula" BORDER="0"> the difference spectrum indicates that the 9-keto C=O stretch of BL is located around 1670-1680 cm-1. After subsequent electron transfer to the bacteriopheophytin HL in [~]1 ps, the state [IMG]f3.gif" ALT="Formula" BORDER="0"> was formed. A sequential analysis and simultaneous target analysis of the data showed a relaxation of the [IMG]f3.gif" ALT="Formula" BORDER="0"> radical pair on the [~]20 ps timescale, accompanied by a change in the relative ratio of the [IMG]f4.gif" ALT="Formula" BORDER="0"> and [IMG]f5.gif" ALT="Formula" BORDER="0"> bands and by a minor change in the band amplitude at 1640 cm-1 that may be tentatively ascribed to the response of an amide C=O to the radical pair formation. We conclude that the drop in free energy associated with the relaxation of [IMG]f3.gif" ALT="Formula" BORDER="0"> is due to an increased localization of the electron hole on the PL half of the dimer and a further consequence is a reduction in the electrical field causing the Stark shift of one or more amide C=O oscillators. }, doi = {10.1529/biophysj.108.130880}, eprint = {http://www.biophysj.org/cgi/reprint/95/3/1268.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/95/3/1268} } @ARTICLE{Pawlowicz10152007, author = {Pawlowicz, N.

We have used time-resolved visible pump/midinfrared probe spectroscopy in the region between 1600 and 1800 cm1 to study the energy transfer and charge separation events within PSII cores. The absorption difference spectra in the region of the keto and ester chlorophyll modes show spectral evolution with time constants of 3 ps, 27 ps, 200 ps, and 2 ns. Comparison of infrared (IR) difference spectra obtained for the isolated antennas CP43 and CP47 and the D1D2-RC with those measured for the PSII core allowed us to identify the features specific for each of the PSII core components. From the presence of the CP43 and CP47 specific features in the spectra up to time delays of 2030 ps, we conclude that the main part of the energy transfer from the antennas to the RC occurs on this timescale. Direct excitation of the pigments in the RC evolution associated difference spectra to radical pair formation of [IMG]f1.gif" ALT="Formula" BORDER="0"> on the same timescale as multi-excitation annihilation and excited state equilibration within the antennas CP43 and CP47, which occur within [~]13 ps. The formation of the earlier radical pair [IMG]f2.gif" ALT="Formula" BORDER="0"> as identified in isolated D1D2 complexes with time-resolved mid-IR spectroscopy is not observed in the current data, probably because of its relatively low concentration.

To investigate this process, we performed transient absorption experiments at 77 K with various excitation conditions on the isolated Photosystem II reaction center preparations from spinach. The results have been analyzed by global and target analysis and demonstrate that at least two different excited states, (Chl(D1)Phe(D1))* and (P(D1)P(D2)Chl(D1))*, give rise to two different pathways for ultrafast charge separation. We propose that the disorder produced by slow protein motions causes energetic differentiation among reaction center complexes, leading to different charge separation pathways. Because of the low temperature, two excitation energy trap states are also present, generating charge-separated states on long time scales. We conclude that these slow trap states are the same as the excited states that lead to ultrafast charge separation, indicating that at 77 K charge separation can be either activation-less and last or activated and slow.} } @ARTICLE{vanRotterdam2002, author = {van Rotterdam, Bart J. and Crielaard, Wim and van Stokkum, Ivo H.

Light absorption by its retinal chromophore initiates a photocycle, driven by trans/cis isomerization, leading to transmembrane translocation of a proton toward the extracellular side of the cytoplasmic membrane. Here we report a study on the photoisomerization dynamics of the retinal chromophore of proteorhodopsin, using femtosecond time-resolved spectroscopy, by probing in the visible- and in the midinfrared spectral regions. Experiments were performed both at pH 9.5 (a physiologically relevant pH value in which the primary proton acceptor of the protonated Schiff base, Asp97, is deprotonated) and at pH 6.5 (with Asp97 protonated). Simultaneous analysis of the data sets recorded in the two spectral regions and at both pH values reveals a multiexponential excited state decay, with time constants of [~]0.2 ps, [~]2 ps, and [~]20 ps. From the difference spectra associated with these dynamics, we conclude that there are two chromophore-isomerizaton pathways that lead to the K-state: one with an effective rate of [~](2 ps)-1 and the other with a rate of [~](20 ps)-1. At high pH, both pathways are equally effective, with an estimated quantum yield for K-formation of [~]0.7. At pH 6.5, the slower pathway is less productive, which results in an isomerization quantum yield of 0.5. We further observe an ultrafast response of residue Asp227, which forms part of the counterion complex, corresponding to a strengthening of its hydrogen bond with the Schiff base on K-state formation; and a feature that develops on the 0.2 ps and 2 ps timescale and probably reflects a response of an amide {II} band in reaction to the isomerization process. }, doi = {10.1529/biophysj.107.121376}, eprint = {http://www.biophysj.org/cgi/reprint/94/10/4020.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/94/10/4020} } @ARTICLE{alisaJPCB09, author = {Rupenyan, Alisa and van Stokkum, Ivo H.

Complexed with NADPH to the enzyme protochlorophyllide oxidoreductase (POR), it is reduced to chlorophyllide, a process that Occurs via a set of spectroscopically distinct intermediate states and is initiated from the excited state of PChlide. To obtain a better understanding of these catalytic events, we characterized the excited state dynamics of PChlide in the solvents tetrahydrofuran (THF), methanol, and Tris/Triton buffer using ultrafast transient absorption in the visible and mid-infrared spectral regions and time-resolved fluorescence emission experiments. For comparison, we present time-resolved transient absorption measurements of chlorophyll a in THE From the combined analysis of these experiments, we derive that during the 2-3 ns excited state lifetime an extensive multiphasic quenching of the emission occurs due to solvation of the excited state, which is in agreement with the previously proposed internal charge transfer (ICT) character of the S I state (Zhao, G. J.; Han, K. L. Biophys. J. 2008, 94, 38). The solvation process in methanol occurs in conjunction with a strengthening of a hydrogen bond to the Pchlide keto carbonyl group. We demonstrate that the internal conversion from the S2 to S1 excited states is remarkably slow and stretches out on to the 700 fs time scale, causing a rise of blue-shifted signals in the transient absorption and a gain of emission in the time-resolved fluorescence. A triplet state is populated oil the nanosecond time scale with a maximal yield of similar to 23%. The consequences of these observations for the catalytic pathway and the role of the triplet and ICT state in activation of the enzyme are discussed.} } @ARTICLE{ISI:000291656900023, author = {Toh, K.

In a recent development, PAS-GAF variants were engineered for use as a near-infrared fluorescent marker in mammalian tissues (Tsien and co-workers, Science, 2009, 324, 804-807). Here, we report the fluorescence quantum yield and photochemistry of two highly-related Bphs from Rps. palustris, RpBphP2 (P2) and RpBphP3 (P3) with distinct photoconversion and fluorescence properties. We applied ultrafast spectroscopy to wild type P3 and P2 PAS-GAF proteins and their P3 D216A, Y272F and P2 D202A PAS-GAF-PHY mutant proteins. In these mutants hydrogen-bond interactions between a conserved aspartate (Asp) which connects the BV chromophore with the PHY domains are disrupted. The excited-state lifetime of the truncated P3 and P2 PAS-GAF proteins was significantly longer than in their PAS-GAF-PHY counterparts that constitute the full photosensory core. Mutation of the conserved Asp to Ala in the PAS-GAF-PHY protein had a similar but larger effect. The fluorescence quantum yields of the P3 D216A and Y272F mutants were 0.066, higher than that of wild type P3 (0.043) and similar to the engineered Bph of Tsien and co-workers. We conclude that elimination of a key hydrogen-bond interaction between Asp and a conserved Arg in the PHY domain is responsible for the excited-state lifetime increase in all Bph variants studied here. H/D exchange resulted in a 1.4-1.7 fold increase of excited-state lifetime. The results support a reaction model in which deactivation of the BV chromophore proceeds via excited-state proton transfer from the BV pyrrole nitrogens to the backbone of the conserved Asp or to a bound water. This work may aid in rational structure-and mechanism-based conversion of constructs based on P3 and other BPhs into efficient near-IR, deep tissue, fluorescent markers.}}, address = {{THOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLAND}}, affiliation = {{Kennis, JTM (Reprint Author), Vrije Univ Amsterdam, Dept Phys \& Astron, Biophys Sect, De Boelelaan 1081, NL-1081 HV Amsterdam, Netherlands.

Thephytochromelight activation mechanism involves isomerization around the C15=C16 double bond of an open-chain tetrapyrrole chromophore, resulting in a flip of its D-ring. In an important new development, bacteriophytochrome (Bph) has been engineered for use as a fluorescent marker in mammalian tissues. Here we report that an unusual Bph, RpBphP3 from Rhodopseudomonas palustris, denoted P3, is fluorescent. This Bph modulates synthesis of light-harvesting complex in combination with a second Bph exhibiting classical photochemistry, RpBphP2, denoted P2. We identify the factors that determine the fluorescence and isomerization quantum yields through the application of ultrafast spectroscopy to wild-type and mutants of P2 and P3. The excited-state lifetime of the biliverdin chromophore in P3 was significantly longer at 330-500 ps than in P2 and other classical phytochromes and accompanied by a significantly reduced isomerization quantum yield. H/D exchange reduces the rate of decay from the excited state of biliverdin by a factor of 1.4 and increases the isomerization quantum yield. Comparison of the properties of the P2 and P3 variants shows that the quantum yields of fluorescence and isomerization are determined by excited-state deprotonation of biliverdin at the pyrrole rings, in competition with hydrogen-bond rupture between the D-ring and the apoprotein. This work provides a basis for structure-based conversion of Bph into an efficient near-IR fluorescent marker.} } @ARTICLE{K.C.Toh07012008, author = {Toh, K. C. and van Stokkum, Ivo H.

Upon illumination, the AppA BLUF domain forms a signaling state that is characterized by red-shifted absorbance by 10 nm, a state known as AppARED. We have applied ultrafast spectroscopy on the photoaccumulated AppARED state to investigate the photoreversible properties of the AppA BLUF domain. On light absorption by AppARED, the FAD singlet excited state FADRED* decays monoexponentially in 7 ps to form the neutral semiquinone radical FADH*, which subsequently decays to the original AppARED molecular ground state in 60 ps. Thus, FADRED* is deactivated rapidly via electron and proton transfer, probably from the conserved tyrosine Tyr-21 to FAD, followed by radical-pair recombination. We conclude that, in contrast to many other photoreceptors, the AppA BLUF domain is not photoreversible and does not enter alternative reaction pathways upon absorption of a second photon. To explain these properties, we propose that a molecular configuration is formed upon excitation of AppARED that corresponds to a forward reaction intermediate previously identified for the dark-state BLUF photoreaction. Upon excitation of AppARED, the BLUF domain therefore enters its forward reaction coordinate, readily re-forming the AppARED ground state and suppressing reverse or side reactions. The monoexponential decay of FAD* indicates that the FAD-binding pocket in AppARED is significantly more rigid than in dark-state AppA. Steady-state fluorescence experiments on wild-type, W104F, and W64F mutant BLUF domains show tryptophan fluorescence maxima that correspond with a buried conformation of Trp-104 in dark and light states. We conclude that Trp-104 does not become exposed to solvent during the BLUF photocycle. }, doi = {10.1529/biophysj.107.117788}, eprint = {http://www.biophysj.org/cgi/reprint/95/1/312.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/95/1/312} } @ARTICLE{Valkunas200917, author = {Leonas Valkunas and Ivo H.

By kinetic modeling of the fluorescence data on chlorophyll and phycocyanin 645 excitation (at 400 and 582 nm respectively), it has been possible to show the excited state energy distribution in the photosynthetic antenna of this alga. Excitation energy from phycocyanin 645 is distributed nearly equally between photosystem I and photosystem {II} with very high efficiency on a 100-ps timescale. The excitation energy trapping times for both photosystem I ([~]30 ps) and photosystem I (200 and [~]540 ps) correspond well to those obtained from experiments on isolated photosystems. The results are compared with previous results for another cryptophyte species, Rhodomonas CS24, and suggest a similar membrane organization for the cryptophytes with the phycobiliproteins tightly packed in the thylakoid lumen around the periphery of the photosystems. }, doi = {10.1529/biophysj.107.113993}, eprint = {http://www.biophysj.org/cgi/reprint/94/6/2423.pdf}, url = {http://www.biophysj.org/cgi/content/abstract/94/6/2423} } @ARTICLE{vanderWeij-DeWitC.D._jp061546w, author = {van der Weij{-}DeWit, C.D. and Doust, A.B. and van Stokkum, I.

This finding questions the possibility of fast energy equilibration among the antenna and the RC, which has been the basic explanation for the measured PSII fluorescence kinetics for more than two decades. In this study, we present time-resolved fluorescence measurements obtained with a streak-camera setup on PSH core complexes from Thermosynechococcus elongatus at room temperature (RT) and at 77 K. Kinetic modeling of the RT data obtained with oxidized quinone acceptor Q(A) reveals that the kinetics are best described by fast primary charge separation at a time scale of 1.5 ps and slow energy transfer from the antenna into the RC, which results in an energy equilibration time between the antenna and the RC of about 44 ps. This model is consistent with structure-based computations. Primary radical pair formation was found to be a virtually irreversible process. Energy equilibration within the CP43 and CP47 complexes is shown to occur at a time scale of 8 ps. Kinetic modeling of the 77K data reveals similar energy transfer time scales in the antenna units and among the antenna and the RC as at RT, respectively, 7 and 37 ps. We conclude that the energy transfer from the CP43/CP47 antenna to; the RC is the dominant factor in the total charge separation kinetics in intact PSII cores.}}, Publisher = {{AMER CHEMICAL SOC}}, Address = {{1155 16TH ST, NW, WASHINGTON, DC 20036 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{van Grondelle, R (Reprint Author), Vrije Univ Amsterdam, Fac Sci, Dept Phys \& Astron, De Boelelaan 1081, NL-1081 HV Amsterdam, Netherlands. van der Weij-de Wit, CD; Dekker, JP; van Grondelle, R; van Stokkum, IHM, Vrije Univ Amsterdam, Fac Sci, Dept Phys \& Astron, NL-1081 HV Amsterdam, Netherlands.}}, DOI = {{10.1021/jp1083746}}, ISSN = {{1089-5639}}, Keywords-Plus = {{EXCITATION-ENERGY TRANSFER; REACTION CENTERS; ELECTRON-TRANSFER; CRYSTAL-STRUCTURE; FLUORESCENCE SPECTROSCOPY; PICOSECOND FLUORESCENCE; LOW-TEMPERATURE; TARGET ANALYSIS; KINETICS; CP47}}, Funding-Acknowledgement = {{Netherlands Organization of Scientific Research (NWO) via the foundation of Earth and Life Sciences (ALW); Foundation for Fundamental Research on Matter (FOM)}}, Funding-Text = {{We thank Eberhard Schlodder (Technische Universitat Berlin) for kindly providing the samples and for useful discussions.
