The multipicosecond nonexponential decay of the electronically excited primary electron donor, P \*, observed in isolated photosynthetic reaction centers, is just as readily explained by multistep homogeneous electron transfer as by single-step heterogeneous transfer. With the aid of a one-antenna-s

In the present work we have carried out a Monte Carlo simulation of a dissociative electron transfer reaction in a polar solvent. In particular, we have chosen as a very simple model the electrochemical reduction of hydrogen fluoride to give a hydrogen atom and a fluoride anion in a dipolar solvent.
A free energy barrier AF+ = 174.2 kJ/mol for the self-exchange electron transfer reaction model Fe+/Fe2+ in water has been calculated by combining Monte Carlo simulations and the statistical perturbation theory. We have shown that, even for those electron transfer reactions that present a very high
