✦ Synopsis

Analytic expressions fitted to cross section data on collisions of H + , H + 2 , H + 3 , H, H 2 , and H -with H 2 are given. The data used are those recommended by Phelps [J. Chem. Phys. Ref. Data 19, 653 (1990)] and additional experimental data, when available, up to a projectile energy of about 100 keV, including new kinds of reactions not treated by Phelps. The analytic expressions are of the semiempirical functional forms proposed by Green and McNeal [J. Geophys. Res. 76, 133 (1971)] and modifications of these, thus making it possible not only to interpolate but also to extrapolate the data to some extent.

The nascent state distributions of OH produced in the reaction H+H20+0H+H2 were probed by fast atom-laser-induced fluorescence experiments. Translationally hot H atoms were formed by photolysis of HI at 250 and 270 nm leading to H+HrO c.m. collision energies E of 176 and 143 kJ/mol. With a calibrat

New high-level quantum chemical calculations have been undertaken to understand the rates and mechanisms of the reactive and associative channels for the reactants C2H2(+) + H2. The reactive channel, which produces C2H3(+) + H, has been shown to be slightly endothermic, confirming earlier calculatio
