Results are presented of a research program concerned with selected aspects of the kinetics, mechanisms and products of reactions involved in photochemical air pollution. Rate constants were determined, using competitive and modulation-phase shift techniques, for the gas phase reaction of O(triplet P) atoms with a variety of organic and inorganic species over the temperature range 296-423K. Products for the gas phase reaction of O(triplet P) atoms with toluene and 1-methylcyclohexene were also studied. The products and mechanisms of the reaction of nitric oxide with methyl peroxy radicals were investigated at 296K using long path infrared spectroscopic and gas chromatographic techniques. The reactions of peroxyacetyl nitrate were investigated in the gas phase with selected constituents of polluted atmospheres, and in the liquid phase with a variety of organics. Chemiluminescence from the reaction of peroxyacetyl nitrate with a series of amines was studied in the liquid phase. The mechanism and products of the gas phase reactions of ozone with a variety of organics was investigated in low pressure flow systems using chemiluminescent and photoionization mass spectrometric techniques. The NO2-catalyzed geometric isomerization of 2-butenes and 2-pentenes was studied over the temperature range 298-400K while an investigation of the NOx-propylene photooxidation system was carried out at room temperature.
