The oxidative evolution ("aging") of organic species in the atmosphere is thought to have a major influence on the composition and properties of organic particulate matter but remains poorly understood, particularly for the most oxidized fraction of the aerosol. Here we measure the kinetics and products of the heterogeneous oxidation of highly oxidized(More)
Understanding the composition of complex hydrocarbon mixtures is important for environmental studies in a variety of fields, but many prevalent compounds cannot be confidently identified using traditional gas chromatography/mass spectrometry (GC/MS) techniques. This work uses vacuum-ultraviolet (VUV) ionization to elucidate the structures of a traditionally(More)
The immense complexity inherent in the formation of secondary organic aerosol (SOA)-due primarily to the large number of oxidation steps and reaction pathways involved-has limited the detailed understanding of its underlying chemistry. As a means of simplifying such complexity, here we demonstrate the formation of SOA through the photolysis of gas-phase(More)
