Abstract
Two different conformers of ethylbenzene radical cations (or a mixture of both conformers) can be stabilized in various freonic matrices. The first conformer retains the geometry of the parent molecule, whereas the second one corresponds to minimum energy. It was shown that the photochemical reactions of the radical cations in various freons at 77 K were not accompanied by a change in their conformational state. The spectral characteristics of ethylbenzene radical cations and the quantum yields of photoinduced charge transfer reactions were determined. The reasons for stabilization of different conformers of the radical cations in different freonic matrices are discussed.
