26. 7 showed that the linear dependence of their transient absorption signal for this system is retained with laser intensities 3 orders of magnitude greater than those used in our experiments.
27. max was obtained by extrapolating to the time of excitation. The corrected values are typically within 5% of the experimental voltage maxima. Decays were first order in solvents of high conductivity such as acetonitrile and butyronitrile. In less conductive solvents, the decay was either a mixture of first and second order or completely second order, depending on the solvent and the laser intensity.
28. 12b Mobilities in other solvents were scaled according to solvent viscosities.

43. -1, which corresponds to aquenching radius of 5.6 Å. With an acceptor concentration of 0.125 M, the quenching time is 400 ps, which is too slow to allow any significant diffusional electron transfer to occur.
44. Naturally our conclusions also depend on the applicability of the diffusion equations solved by O and by HN to our results. These equations involve some approximations as discussed in the text. It is possible that improvements of the approximations could suggest a modified interpretation.
