The green function method in the theory of nuclear and electron spin polarization. II. The first approximation and its application in the CIDEP theory

Abstract

The present paper deals with a further development of the method of calculating nuclear and electron spin polarization based on the Green function formalism specifying the character of the relative motion in a pair of radical centers. In the first approximation with respect to the exchange interaction influence the calculations of the desired quantities are reduced to matrix operations. A theory of chemical polarization of electrons serves to illustrate the method. Calculations of this effect in micellar radical pairs are performed. It is shown that quantum oscillations are possible here depending on the magnitude of the external magnetic field induction.
