Sink-algorithms for the simulation of electron transfer kinetics

Procedures for computing Green's function for the equations of the two-level Zusman model and the stochastic Jortner–Bixon model are proposed. The algorithms for the numerical simulation of electron transfer kinetics in donor-acceptor complexes in polar solvents are developed. The efficiency of these algorithms is analyzed and compared with the efficiency of the recrossing algorithm developed earlier. Test simulations of the reaction kinetics are performed; their results show a good correspondence with the known analytic estimates in some particular cases.
