Abstract. From the experimental data for a series of donor-acceptor complexes (hexamethylbenzene/tetracyanoethylene, isodurene/tetracyanoethylene and pentamethylbenzene/tetracyanoethylene) the main energy parameters of charge recombination (the free energy gap, the reorganization energy of the medium and the intramolecular vibrational modes) have been determined. In the framework of the multichannel stochastic model the charge recombination kinetics in excited donor-acceptor complexes have been calculated. The influence of the dielectric and relaxation characteristics of the solvent on thekinetics has been investigated.

Key words: charge transfer, multi-channel stochastic model, the reorganization energy, kinetics, polarity.
