Short summary
Simulating the composition of organic aerosol particles formed by chemical reactions in the atmosphere (secondary organic aerosol, SOA) is challenged by the enormous complexity of molecular species and chemical processes involved. We report spectroscopic (NMR) and chromatographic data for SOA samples obtained using a flow reactor designed to simulate photochemical ageing. We show that the composition of aged biogenic (monoterpene) SOA particles closely resembles that of ambient aerosols.
