✦ Synopsis

Kinetic energy releases from the unimolecular 1~2 CD,) elimirzxtion reactions of energy-selected x 'Bag CzHz <CzDz) I~JW been obtsincd by a photoelectron-photoion coincidence technique_ The energ-releases susgest a 1.1 elimination and 3~ compatible xrith the presence of a small reverse activation energy barrier of the order of 0.02 eV. Such a barrier was indicatcd by a detailed 3b initio study of this dissociation and the present results are discussed in the light ofthis thcoreticd rrci~tmcnr.

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
