Coupled-channel statistical theory of the N(2D)+H2 and O(1D)+H2 insertion reactions

A detailed statistical theory of atom–diatom insertion reactions is derived by combining the early statistical ideas of Pechukas and Light with the coupled-channel capture theory of Clary and Henshaw. The theory is applied to the N(2D)+H2 and O(1D)+H2 reactions and found to give results in good agreement with the exact quantum mechanical integral cross sections reported recently by Honvault and Launay.
