Possible mechanisms of charge phototransfer are considered in heterogeneous systems with participation of dipole particles. Correlations between kinetic parameters of charge transfer photoprocesses and the corresponding thermal processes are obtained. Analytic expressions for extinction coefficients of the following processes under viewing are obtained : light absorption in the volume of the system by individual particles with transition of these particles into an electronically excited state; light absorption by the reacting particles with direct outer sphere electron transfer between the particles; light absorption by the particles adsorbed on the electrode surface with transition of these particles into an excited state; light absorption by the particles close to the electrode surface with electron phototransfer from the particle to the electrode; light absorption by the particle with transition into adsorbed state.
