Abstract
The reaction of O(3P) atoms with methylacetlyene was studied at three temperatures between 260 and 350 K by means of a CO laser resonant absorption method. The CO formed in the reaction had a Boltzmann vibrational temperature of about 2400 K and carried only 1.9 ± 0.2% of the total available reaction energy, independent of the initial temperature of the system. Good agreement was obtained between the observed CO population distribution and that predicted by a simple statistical model, with the assumption that CH2CH, and not C3H4, was formed initially in the reaction. The kinetics of the CO formation along with the results from the statistical indicate that the dominant primary step of the reaction is: O(3P) + CH3C2H → CH3CH + CO.
