β¦ Synopsis
The general effect of back energy transfer is to reduce the apparent quenching constant which is an important parameter in the interpretation of energy transfer data. However, this interpretation may be erroneous when possible diffusion effects and the existence of nonuniform configurational distributions are not taken into account.

Starting from Smoluchowski's hypothesis, a simple algorithm is developed in order to obtain the apparent rate constant at large values of time, t, with some physical and chemical processes, as in the case of diffusion controlled reactions. Some practical examples are illustrated, assuming nonuniform
Fluorescence quenching induced by electron transfer was studied by measuring the transient effect in decay curves and also the changes in stationary intensity with quencher concentration. The results were analyzed using the Collins-Kimball model of diffusion-controlled reactions, yielding the reacti
