Measurements of the gas-phase production rates of alpha-nitratoacetone, propylene glycol dinitrate, 2-hydroxy propyl nitrate, and 2-nitrato propyl alcohol (2-NPA) in a C3H6/N2O5/air dark reaction and a C3H6/NOX/air irradiation are reported. The probable operative reaction mechanisms are discussed and the branching ratios for peroxy radical reaction with no via RO2 + NO -> RONO2 versus RO2 + NO -> RO +NO2 are estimated for CH3CH(OO)CH2OH and CH3CH(OH)CH2OO radicals.
