Abstract
Ultrafast intermolecular electron transfer (0.1-0.2 ps) was observed for xantheme dyes in electron-donating solvents. Rates were limited by ultrafast nuclear relaxation not by solvent longitudinal relaxation, (470 mn) and AN (405 nm) and DMA (470 nm) cations in the subpicosecond timescale. From the recovery of ground-state depletion and decay of cation radicals, the reverse ET was also found to be fast, i.e., 4.0 ps in NB/DMA and 2.7 ps in NB/AN.
