Abstract
A number of physical phenomena and observables can be accounted for and are consistent with the superexchange mechanism for the primary electron transfer in the reaction centre of Rb.sphaeroides. These include electric field effects on the quantum yield and polarization of the prompt fluorescence, the unidirectionality of the charge separation and the magnetic properties and recombination dynamics of the primary radical pair. A rationalization for the prevalence of the superexchange mechanism in the primary charge separation is provided on the basis of a kinetic optimization criterion in conjunction with energy constraints on the medium reorganization energy.
