Further development of the diffusional model of the radical pair is suggested. A function is proposed for the exponential distribution of the diffusional trajectories of the radicals in a radical pair. By this function, the differences in the populations of nuclear spin levels in the molecules are calculated for the S, T and U precursor pairs. The equations which express the relationship between the theoretically calculated population differences and the experimentally determined enhancement coefficients are derived.
