FIGURE 9.

(a) Solid circles represent reconstructed experimental fluorescence kinetics (TCSPC) of BBY (see text for details). Solid and dashed lines represent simulated decay curves, using the two RC models of Fig. 8, a and b. Electron transfer to the quinone is implemented by assuming irreversible transfer from RP2 with a rate constant of (200 ps)⁻¹. The thick lines (1) refer to model 8 (a), the thin ones (2) to model 8 (b). For the solid lines a hopping time of 17 ps is taken and an infinitely fast hopping time for the dashed ones. (b) Solid circles represent reconstructed experimental fluorescence kinetics (TCSPC) of BBY (see text for details). Solid and dashed lines represent simulated decay curves, using the two core models of Fig. 8, c and d. The thick lines (3) refer to the model in Fig. 8 c, the thin ones (4) to the model in Fig. 8 d. For the solid lines a hopping time of 17 ps is taken. For the dashed lines a hopping time of 13.4 ps is taken for case 3 (thick dashed) and 0 ps for case 4 (thin dashed).
