✦ Synopsis

The vibrational predisso&tion spectra of (C, H4)2 and Ar-C? H4 hwc been measured using a molecular beam apparatus and ;t tunable infrared laser (an optical parametric oscillator), near the vg (==3100 cm-') and 1~11 (=2990 cm-') modes of ethylene. The spectra are not homogeneously broadened and show considerable rotational structure at 0.9 cm-' resolution. Analysis of the Ar-&Ha spectra places the w=on in the ethylene plane along the perpendicular bisector of the double bond at i distance of 3.6 i_

The successive C-H bond dissociation energies of CH,, &Hz. C2H4, and H&O (ketene) are determined using large basis sets and a high level of correlation treatment. For CHI, C2H2, and C2H4 the computed values are in excellent agreement with experiment. Using our results we recommend 107.9 +2.0 and 96.

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
