Abstract

Time-resolved spectroscopy in conjunction with magnetic-field-dependent recombination dynamics of the primary radical ion pair in reaction centers of Rb, sphaeroides R26, were used to analyze the mechanism of electron transfer from the bacteriochlorophyll dimer in its excited singlet state (1P*) to bacteriopheophytin (H). This analysis provides evidence against the participation of the accessory bacteriochlorophyll (B) as a kinetic intermediate and thus favours a single-step electron transfer, which is mediated by superexchange electronic interactions.
