    Notes: The conventional method of statistical mechanics leading to integral kinetic equations for bimolecular energy quenching collapsed when used for evaluation of concentration corrections to the Stern–Volmer constant in the diffusion control limit. These corrections obtained by Felderhof and Jones for uniform quenching within transparent reacting spheres are much larger than in other theories, including exact solution available for irreversible energy transfer from immobile donor to independently moving acceptors. This results in a qualitative distortion of the Stern–Volmer constant dependence on the excitation lifetime at any finite concentration of quenching spheres. © 2000 American Institute of Physics.

    Notes: A many-particle consideration of diffusion-influenced reversible pseudo-first order reaction A+B(r harp over l)C+B is presented. It is shown that the lowest order (in concentration) of the memory matrix is not sufficient for describing the binary kinetics of the reaction. Binary kinetic equations describing both stationary and nonstationary stages of the kinetics have been obtained using diagrammatic representation and selecting the necessary diagrams. Comparison with the fully renormalized kinetic theory is made by considering the contact approximation for reactivity. © 1999 American Institute of Physics.

    Notes: We studied the reversible transitions between two levels of excited molecule stimulated by encounters with other solutes. The inter-system crossing results in either quenching or trapping of excitation depending on the relationship between the lifetimes of the levels. In the particular case of an immobile excited molecule and equal lifetimes, an exact solution of the problem was given which is valid for arbitrary concentration of solutes. We compared the fluorescence quantum yield obtained with this solution, superposition approximation and integral encounter theory. Our main conclusion is that for equal lifetimes the latter has an advantage, even in small concentration limits and is out of competition when the lifetime of the primary excited level is shorter than another. © 1998 American Institute of Physics.
