Description
Summary:The CIDNP formation on radical recombination in homogeneous solutions is considered. The Coulomb interaction of radicals and electron—spin relaxation are taken into account. The behaviour of CIDNP kinetics and its dependence on some radical parameters and on experimental conditions are found out on the basis of numerical calculations and a simple analytical model. It is shown that CIDNP can non-monotonously depend on time and change sign under certain conditions. The CIDNP kinetics behaviour depends qualitatively on whether the initial state of a geminate radical pair (GRP) is reactive or not and on the validity of Kaptein's rules.
