Investigation of the CH3 + NO reaction in shock waves

Article abstract of DOI:10.1002/bbpc.19940980516

The reaction of CH₃ + NO was investigated behind incident shock waves at temperatures between 1300 K and 2080 K. The formation of H atoms and of HCN was studied by time resolved UV absorption and by IR-emission. OH measurements of Hoffmann et al. were reevaluated with the rate constant of this work. The rate constant for the reaction of CH₃ + NO can be expressed by k = (4.0 ± 0.8)·10¹² exp(-(8500 ± 500) K/T) cm³ mol^-1 s^-1. HCN was found to be the main final product of the reaction of CH₃ + NO in the temperature range covered. The contribution of the H forming channels is around 20-25% to the main channel.
