Products and mechanisms for the gas-phase reactions of NO3 radicals with a series of alkenes in air have been studied. The experiments with propene, isobutene, trans-and cis-2- butene, 2-methyl-2-butene, and 2, 3-dimethyl-2-butene were carried out at 295 f 2 K and 740* 5 Torr in a 480-L Teflon-coated reaction chamber where NO3 was generated by the thermal dissociation of N2O5. Reactants and products were observed to produce nitroxy- ...
