Temporal changes of the EXAFS in response to a temperature jump (at t = 0). (a) Fourier transforms of k3-weighted EXAFS oscillations of the Mn complex of PSII multilayers exposed to 320 K for 0, 4 and 180 min. Thin lines, experimental data; thick lines, simulations. (b) Time courses of the coordination numbers of six shells of backscatterers resulting from a joint fit of eight EXAFS spectra. The points are the coordination numbers as determined by the joint fit; the solid lines were calculated based on the consecutive reaction shown in Fig. 6. The good agreement between calculated and experimentally determined coordination numbers confirms the validity of the reaction scheme used (Pospisil et al., 2002). |
