On spin-exchange and electron-transfer rates in bacterial photosynthesis
Abstract
A discrepancy is explored regarding the spin exchange integral estimated from magnetic field effects on recombination of the bacteriochlorophyll dimer cation (Bchl)2+ and the bacteriopheophytin anion Bph- and the measured electron transfer rate between Bph and electronically excited (Bchl)2. In one explanation considered here there are two sites for the electron or for the hole, with a hopping between sites.
