Abstract

An expression for the initial chemically induced dynamic electron polarization produced according to a triplet mechanism under the conditions of pumping by polarized light has been obtained under the assumption that the fluctuations of the orientation of a molecule in a liquid have the character of an uncorrelated Markov process. The expression obtained is valid for arbitrary values of the magnetic field strength and the viscosity of the solvent. Numerical calculations of the chemically induced dynamic electron polarization have been carried out for slow molecular rotations and in weak magnetic fields.
