Abstract
The dissociation of energy-selected c-C 3H 6S + was investigated in a region 10.2–10.9 eV with a threshold photoelectron-photoion coincidence technique. Branching ratios and average releases of kinetic energy for channel c-C 3H 6S + → H 2CS + + C 2H 4 were derived from coincidence mass spectra. The measured small releases of kinetic energy near the appearance onset agree with statistical calculations; a linearly extrapolated threshold at 10.39 ± 0.01 eV agrees with a predicted energy 10.35 eV with the G aussian-3 method. We discuss plausible mechanisms for c-C 3H 6S + dissociating to CH 3CS + + CH 3 based on G3B3 calculations to rationalize the absence of CH 3CS + signal in these experiments.
