Table 2. Estimated Electron Transfer Times Obtained from Simulations of Electron Propagation along the Trp-Tetrad^a.

dataset	ET2 (ps)	ET3 (ps)	ET4 (ps)

630 ps (Figure 5b)	200	260	60

^aResults are shown for the numerical fits of the solution of eq 1 to the computed data for the 1-ns simulation and 630-ps simulations, averaged over 50 and 27 independent simulations, respectively. In the latter case only those simulations where Trp_CH^·+ or Trp_DH^·+ obtained an occupancy of at least 0.3 were considered. The values have been rounded to the nearest 10 ps.
