Superexchange versus an intermediate BChl− mechanism in reaction centers of photosynthetic bacteria

Abstract

Kinetic and singlet-triplet data are used to treat the mechanism of electron transfer for BChl*_2-BChl-BPh in bacterial photosynthetic reaction centers. The data favor a two-step transfer rather than a superexchange single step.
