Abstract
The gas-phase reactions, C(1D)+NO and C(1D)+O2 have been studied over the 50–296K range using a Laval nozzle reactor. C(1D) atoms were produced by CBr4 photolysis. A tracer technique was employed to follow the kinetics by adding H2 or CH4 to the flow. H-atoms produced by the C(1D)+H2/CH4 reactions were detected by laser-induced fluorescence. Rate constants for the C(1D)+O2 reaction show little variation with temperature, whereas rate constants for the C(1D)+NO reaction increase rapidly below 100K. Numerical simulations were performed to evaluate the influence of secondary reactions.
