This work provides the first fundamental laboratory data to evaluate SOA (secondary organic aerosol) production from styrene and NO3 chemistry. Additionally, the formation mechanisms of aromatic organic nitrates (ONs) are reported, highlighting that previously identified nitroaromatics in ambient field campaigns can be aromatic ONs. Finally, the hydrolysis lifetimes observed for ONs generated from styrene and NO3 oxidation can serve as experimentally constrained parameters for modeling hydrolysis of aromatic ONs in general.
