Products and mechanisms for the gas-phase reactions of NO{sub 3} 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 {plus minus} 2 K and 740 {plus minus} 5 Torr in a 480-L Teflon-coated reaction chamber where NO{sub 3} was generated by the thermal dissociation of N{sub 2}O{sub 5}. Reactants and products were observed to produce nitroxy-nitroperoxy intermediates that decayed with formation of carbonyl, nitroxycarbonyl, nitroxy alcohol, and dinitrate species. The product distribution was found to be dependent on the alkyl substitution pattern around the double bond. Evidence was also found of a reaction between NO{sub 3} and organic peroxy radicals with a rate constant measured in the case of the 2,3-dimethyl-2-nitroxy-3-peroxybutane radical to be of the order of 5 {times} 10{sup {minus}12} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1}.
