title = "Unexpected epoxide formation in the gas-phase photooxidation of isoprene",
abstract = " Emissions of nonmethane hydrocarbon compounds to the atmosphere from the biosphere exceedthose from anthropogenic activity. Isoprene, a five-carbon diene, contributes more than 40% ofthese emissions. Once emitted to the atmosphere, isoprene is rapidly oxidized by the hydroxylradical OH. We report here that under pristine conditions isoprene is oxidized primarily tohydroxyhydroperoxides. Further oxidation of these hydroxyhydroperoxides by OH leads efficientlyto the formation of dihydroxyepoxides and OH reformation. Global simulations show an enormousflux-nearly 100 teragrams of carbon per year-of these epoxides to the atmosphere. Thediscovery of these highly soluble epoxides provides a missing link tying the gas-phase degradationof isoprene to the observed formation of organic aerosols.",
