摘要：

Femtosecond intermolecular electron (ET) transfer dynamics were studied by time-resolved fluorescence up-conversion technique in contact systems of oxazine dyes in electron-donating solvents. Clearly non-exponential ET time dependence was observed in aniline and explained by the effects of both solvent reorientation and nuclear motion of the reactants. Single exponential processes were measured for nile blue (less-than-or-equal-to 160 fs) and oxazine 1 (less-than-or-equal-to 280 fs) in N,N-dimethylaniline. The rate of ET is explained to be limited only by ultrafast nuclear relaxation.
