Notes:
The C2v, potential energy curves for the interaction of Ga, Ga+, and Ga2+ with the hydrogen molecule were calculated using the pseudopotential method of Durand et al. and triple-ζ gaussian basis sets. Electronic correlation has been taken into account by MRCI + MP2 calculations. We studied the 2B2(4p), 2A1(4p), 2A1(5s), and 2B2(5p) surfaces for the Ga + H2, the 1A1, 3B2, and 1B2 surfaces for Ga+ + H2 and the 2A1,(4s), 2B2, and 2A1(5s) surfaces for the Ga2+ + H2 reaction. We first analyzed the unrelaxed H2 approach to the metallic center, followed by the angle relaxation. The reactivity in all the interactions studied are analyzed with a model mechanism, previously proposed by us. © 1992 John Wiley & Sons, Inc.
