On product state distributions in triatomic unimolecular reactions Part III. Barrier processes with a path defined by bent geometries

Abstract

We develop an analytical theory of state distributions in the products of three-atom unimolecular reactions involving a barrier and a dissociation path defined by bent geometries. The approach combines transition state theory (TST), kinematic rotations (KR) and the linear transformation model (LTM), published recently. Its predictions are compared with quasiclassical trajectory calculations on a model potential energy surface.
