Electron Transfer between Molecules in Solution

Abstract

The rate of electron transfer between molecules in solution especially in the weak coupling case are formulated in the form of overlap integral between two quantum spectra obtainable experimentally. The direction of electron transfer between molecules is predicted from the sign of a theoretical quantity and the irreversible property on the electron transfer between molecules in solution is elucidated. The experimental confirmations of the theory are obtained from Leonhardt-Weller’s and Ishitani-Nagakura’s investigations.
