Kinetics of CH Radicals with O2: Evidence for CO-Chemiluminescence in the Gas Phase Reaction
Abstract
The methylidyne (CH) radical is known to be an important reaction intermediate during the oxidation of hydrocarbon fuels. Its reactivity with combustion species such as 02, 0-atoms, C02, N2, N20, NO, N02, NH3 and numerous other hydrogenous, carbonaceous and sulfurous species is well reviewed and compiled in the literature. However, the nature of product branching, energy disposal and its theoretical treatment has been examined in only a few of these reactions; (CH + NO) and (CH + N2) reactions by far being the most studied systems. Particularly lacking in the literature is information on the production of electronically excited state species. The Air Force Research Laboratory is interested in the methylidyne and the methylene (CH2) radical reactions with O2 and 0-atoms since they are thought to play an important role in the production of ultraviolet/visible chemiluminescence when rocket plumes interact with the earth's ambient atmosphere.
