The reactions of O(3P) atoms with allene and methylacetylene: O+CH2=C=CH2 {A figure is presented} CO+C2H4,ΔH10 = -119.4 kcal/mole, O+CH3-C{A figure is presented}CH {A figure is presented} CO+C2H4,ΔH20 = -117.8 kcal/mole were studied at 293 K with a CO laser resonant absorption and a discharge-flow GC-sampling method. The CO formed in reaction (1) was found to have a vibrational temperature of 5100 ± 100 K, compared with 2400 ± 200 K in (2). The good agreement between the observed CO vibrational distributions and those predicted by simple statistical models indicates that the reaction energies were completely randomized.The present results also showed unambiguously that CH3CH, instead of C2H4, was produced initially in reaction (2).
