Diffusion-influenced reversible geminate recombination in one dimension. III. Field effect on the excited-state reaction
We obtain exact analytic solutions of the diffusion-influenced excited-state reversible geminate recombination reaction, A(*)+B<---->(AB)(*), with two different lifetimes and quenching under the influence of a constant external field in one dimension. These fundamental solutions generalize two previous results [Kim , J. Chem. Phys. 111, 3791 (1999); 114, 3905 (2001)] and provide us with the insight necessary to analyze their specific relations and asymptotic kinetic transition behaviors. We find that the number of kinetic transitions can be changed due to interplay between the field strength and lifetimes. Unlike the previous works, the number of lifetime dependent transitions is found to be one or zero. On the other hand, the number of the field dependent transitions becomes two, one, or zero. We find a new pattern of kinetic transition e(t)-->t(-1/2)-->e(t) when there is only one field dependent transition. (C) 2004 American Institute of Physics.
