An ab initio MP4 study has been made of the potential energy surface of the H + OCS reaction. Minima and saddle points leading to formation of OH +CS or SH + CO were found. Stationary points were located using the 6-31 G# basis set at the ROHF and UMP2 levels of theory, with energy refinements at th

Preliminary results of ab initio unrcstiictcd Hnrtree-Fock calculations for the potential enerfiy surfact for the reaction N' + Hz + Nil+ + H ae reported. For the collinear approach of Nf to Hz, the 3 - x surface has no activation barrier and has a shallow well (n. 1 eV). For perpendicular approach
Both the abstraction and substitution mechanisms for the reaction of NHf with H-and the abstraction mechanisms for the reaction with LiH in the gas phase have been investigated by theoretical methods. LiH results to be a better reagent and reactions with and without scrambling are competitive in acc
Optimised geometries and harmonic vibrational frequencies for possible products and intermediates of the reaction of BH2 with NO, calculated at the HF/6-31G\* level of theory, are presented. Energies calculated using these optimised geometries at the HF, MP2 and MP4SDQ levels of theory are given.
