NON-POISSON STATISTICS OF REACTIVE EVENTS AND NONEXPONENTIAL KINETICS

consider a model of a chemical reaction where the transition is possible only if the environment of the reacting complex attains a certain configuration. for example, electron transfer between two electronic states occurs when a fluctuation of the environment:brings these states into resonance. Non-Poisson statistics of reactive events may lead to nonexponential kinetics characterized by short- and long-time rate constants. The transition from the nonadiabatic to adiabatic (environment-controlled) regime of the reaction is shown to have different character in the cases of attractive and repulsive statistics.
