Abstract

Time-resolved picosecond emission spectroscopy is used to examine the kinetics of intramolecular charge transfer in bis-(4-aminophenyl) sulfone in ethanol solutions as a function of temperature. The population decay of the local excited state is compared to both an exponential decay and a decay of the form I(t) = sin-1 (e-t/τS); the latter function has been proposed to be applicable in the limit of solvent-controlled electron-transfer reactions and is found to provide a good fit to the experimental data. The calculated decay times, τS, are similar to the longitudinal relaxation time of the solvent, τL, defined by τL = τDεmw0.
