Title: Branching ratio for the hydrogen atom product channel in the reaction of ground-state atomic oxygen with ethylene

Abstract

The branching ratio, ..cap alpha../sub 1/, for the H + C/sub 2/H/sub 3/O product channel of the O(/sup 3/P) + C/sub 2/H/sub 3/O reaction was determined from measured H- and O-atom profiles in this flash photolysis-resonance fluorescence study. The relative detection sensitivity of the system for H and O atoms was determined experimentally. A chemical model was used to describe the reaction mechanism together with the relative detection sensitivity, and a value of ..cap alpha../sub 1/ = 0.27 +/- 0.05 was derived at 300 K. At higher temperatures, the value of ..cap alpha../sub 1/ appears to increase slightly. Possible reasons for this increase are discussed. 30 references, 2 figures, 7 tables.
