| Abstract: | Kinetic energy releases from the unimolecular H2 (D2) elimination reactions of energy-selected Ã2B3gC2H4+(C2D4+) have been obtained by a photoelectron-photoion coincidence technique. The energy releases suggest a 1,1 elimination and are compatible with the presence of a small reverse activation energy barrier of the order of 0.02 eV. Such a barrier was indicated by a detailed ab initio study of this dissociation and the present results are discussed in the light of this theoretical treatment. |
