Abstrakt: A method of calculating electron and nuclear spin polarization based on the Green function formalism which specifies the character of the relative motion of radical centers is suggested. In a zero approximation with respect to the exchange interaction influence the calculations of the desired quantities are reduced to matrix operations. To illustrate the possibilities of the method, two particular examples are given. In the first example the CIDNP kinetics is calculated with allowance for electron spin relaxation, in the second one the relationship is established between the form of the spectrum line of the stimulated polarization of nuclei and the character of the relative motion of radicals in solution.
