On the theory of the radical radiation formation in a solid host

The calculation of the radical formation rate constant in solid organic compounds is carried out. This formation is a result of the cleavage of the hydrogen atom from the carbon atom via a radiationless electronic transition in an electronically excited molecule. The electronic transition is supposed to be stipulated by the nonadiabaticity operator and the perturbation theory with respect to this operator is supposed to be applicable. The vibrational interaction of an electronically excited molecule with the host environment is assumed not to be small. The calculation is carried out within the framework of a model in which the whole molecule is represented by a CH group this being treated as a Morse oscillator. The specific features of the different substances in such a model are simulated by different values of the CH bond parameters.
