Abstract
In this paper we consider long-range electron transfer (ET) in a structurally rigid, solvent-free, DBA supermolecule, which consists of a bridged (B) electron donor (D) and electron acceptor (A), exploring the excess vibrational energy (E) dependence of the microscopic ET rates from photoselected states. We have studied charge separation (DBA) * →D + BA - and charge recombination D + BA - →DBA in an isolated supermolecule where the charge-transfer D + BA - state constitutes the lowest spin-allowed electronic excitation. The energy-dependent microscopic ET rates in the statistical limit of the radiationless transitions theory were expressed in terms of the averaged Franck-Condon density, for which quantum and classical expressions were presented in the harmonic approximation
