... Recent research of the Laboratory of Photochemistry is concerned mainly with the problems of mechanisms and kinetics of several kinds of photoreactions in homogeneous media and in organized molecular systems. ... Electron Transfer Mechanism Exciplexes . Chain ion-radical reactions of photosubstitution in aromatic compounds . ... Electron transfer mechanisms of exciplex and excimer formation reactions kinetics were studied by fluorescence spectroscopy and flourescence kinetics methods. ...
