Excited-State Reversible Geminate A~(*) + B reversible C~(*) + D Reaction in Two Dimensions

摘要

The reversible geminate transfer reaction, A~(*) + B reversible C~(*) + D, has been studied in two dimensions. For the excited-state transfer reaction with two different lifetimes and quenching, the exact analytical Green functions have been generalized for an arbitrary initial condition in the Laplace domain. Long-time asymptotic behavio rs of survival probabilities have been analyzed in the time domain as well as short-time expressions. The two-dimensional survival probabilities have been found to show logarithmic decay behaviors of (ln t)~(-1) or t~(-1) (ln t)~(-2) at long times, depending on two lifetimes.
