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.
