Addition of ethyl radicals to nitric oxide

Mixtures of methyl and ethyl radicals have been generated at 295 K in a fast flow discharge system by addition of hydrogen atoms to ethylene in helium at total pressures from 6 to 15 Torr (1 Torr = 133 N m–2). Mass spectrometric analysis of the reaction products both with and without added nitric oxide has provided data, numerical analysis of which has given the rate constants of the following reactions, [graphic omitted]
