Dynamics of reaction of O with H₂ and its isotopic variants in different rotational excited states

Scalar properties and vector correlations of the reactions O+H₂ →OH+H, O+HD→OH+D, O+DH→OD+H, andO+D₂ →OD+D at collision energies of 25 and 34.6 kcal/mole have been studied via quasi-classical-trajectory (QCT)method based on a BMS1 potential energy surface (PES). Generalized polarization-dependent differential cross sectionand the distributions of the dihedral angle at the collision energy of 34.6 kacl/mole are presented. The calculated resultsindicate that both reagent rotational angular momentum and the mass factor have a significant influence on the scalarproperties and vector correlations of the title reactions.
