EXPERIMENTAL TESTING OF MOLECULAR DYNAMIC FUNCTIONS OF PAIRS BY THE ISOTOPE SELECTIVITY OF RADICAL RECOMBINATION

A method for experimental testing of the molecular dynamic function f( t), which describes the generation of reencounters in a dynamic pair o f molecular particles, has been developed. The method is based on the analysis of isotope separation in spin selective reactions of a radica l pair. The f(t) function derived from the solution of the diffusion e quation with physically rigorous initial and boundary conditions descr ibes experimental results much better than the well-known Noyes functi on. Conditions that make it possible to increase the efficiency of iso tope separation in spin selective reactions are formulated.
