Kinetic modelling of methyl radical reactions with formaldehyde and isobutane. Reinterpretation of existing data obtained by molecular modulation spectrometry

Previously published data on the rates of reaction of methyl radicals with formaldehyde and isobutane have been re-analysed by kinetic modelling. It is shown that the rate constant for the initial abstraction reaction was significantly overestimated in each case, owing to the neglect of important secondary radical-radical reactions. The revised rate constants are reported and compared with the results of other investigators.
