Estimation of rate coefficients and branching ratios for reactions of organic peroxy radicals for use in automated mechanism construction
TL;DR: In this paper, the branching ratio data for the bimolecular reactions of organic peroxy radicals with NO, NO2, NO3, OH and HO2 are reviewed for the self-reaction and cross-reactions with other RO2 radicals.

Tropospheric Aqueous-Phase Oxidation of Isoprene-Derived Dihydroxycarbonyl Compounds
TL;DR: An aqueous-phase oxidation scheme was developed on the basis of the experimental findings to show their potential to contribute to the aqSOA formation, and it can be expected that the main contribution to aqsoA occurs via acid formation while other short-chain oxidation products are expected to back-partition into the gas phase to undergo further oxidation there.

TL;DR: It is reported here that under pristine conditions isoprene is oxidized primarily to hydroxyhydroperoxides, which leads efficiently to the formation of dihydroxyepoxides and OH reformation, which provides a missing link tying the gas-phase degradation of isoprenes to the observed formation of organic aerosols.
