متن کاملCONDENSED ATMOSPHERIC PHOTOOXIDATION MECHANISMS FOR ISOPRENE by
Two condensed mechanisms for the atmospheric reactions of isoprene, which differ in the number of species used to represent isoprene’s reactive products, have been developed for use in ambient air quality modeling. They are based on a detailed isoprene mechanism that has recently been developed and extensively evaluated against environmental chamber data. The new condensed mechanisms give very ...
متن کاملSecondary organic aerosol formation from isoprene photooxidation.
Recent work has shown that the atmospheric oxidation of isoprene (2-methyl-1,3-butadiene, C5H8) leads to the formation of secondary organic aerosol (SOA). In this study, the mechanism of SOA formation by isoprene photooxidation is comprehensively investigated, by measurements of SOA yields over a range of experimental conditions, namely isoprene and NOx concentrations. Hydrogen peroxide is used...

متن کاملUnexpected epoxide formation in the gas-phase photooxidation of isoprene.
Emissions of nonmethane hydrocarbon compounds to the atmosphere from the biosphere exceed those from anthropogenic activity. Isoprene, a five-carbon diene, contributes more than 40% of these emissions. Once emitted to the atmosphere, isoprene is rapidly oxidized by the hydroxyl radical OH. We report here that under pristine conditions isoprene is oxidized primarily to hydroxyhydroperoxides. Fur...
