Ab initio techniques inclusive of electron correlation (MP2) are used to study the gas-phase dimerization of water tetramers (T) into octamers (0), which is relevant to a model for the specific heat of liquid water. The T species has one basic structure, whereas three different conformations for the

Temperature dependenrrs of cqniti& rium constants were obtained by a standard statistical-thermodynamic treatment for which all necessary molecular tortstants were generated by the ab initio SCF calculations of double zeta qual
The reactants, products, and saddle point for the reaction H, + CN 4 H + HCN have been studied by ab initio calculations. The computed structures, frequencies, and energetics are compared directly to available measurements and, indirectly, to experimental rate constants. The theoretical rate constan
