Reactions of methyl- and ethylperoxy radicals with NO studied by time-resolved negative ionization mass spectrometry

The rate constants for the gas-phase reactions of methyl- and ethylperoxy radicals with NO were studied at room temperature and 4 Torr of pressure. The alkyl peroxy radicals were generated by the reaction of corresponding alkyl radicals with excess O2, where alkyl radicals were prepared by laser photolysis of several precursor molecules.
