Environmental context Atmospheric aerosols have profound effects on the environment
through several physicochemical processes, such as absorption and scattering of sunlight …

Organic oxidation reactions in the atmosphere can be challenging to parse due to the large
number of branching points within each molecule's reaction mechanism. This complexity …

The mechanism and kinetics of reactive oxygen species (ROS) formation when atmospheric
secondary organic aerosol (SOA) is exposed to solar radiation are poorly understood. In this …

Organic alkoxy (RO) and peroxy (RO2) radicals are key intermediates in multiphase
atmospheric oxidation chemistry, though most of the study of their chemistry has focused on …

The heterogeneous reactions of hydroxyl radicals (OH) with squalane and bis (2-ethylhexyl)
sebacate (BES) particles are used as model systems to examine how distributions of …

The study of the chemistry underlying secondary organic aerosol (SOA) formation is
complicated by the large number of reaction pathways and oxidation generations available …

The photolysis of o-tolualdehyde by natural sunlight has been investigated at the large
outdoor European Photoreactor (EUPHORE) in Valencia, Spain. The photolysis rate …

Synchrotron radiation allows ionization of organic molecules near threshold with minimal
excess internal energy. As such, synchrotron vacuum ultraviolet (SVUV) photoionization is a …

Secondary organic aerosol (SOA) particles result from the condensation of oxidized volatile
organic compounds (VOC) and consist of a complex mixture that is not conducive to …

Recent studies have shown that 254 nm light can be used to generate organic aerosol from
iodoalkane/air mixtures via photodissociation of the C–I bond and subsequent oxidation of …
