Laboratory simulations of benzene oxidation and formation of highly oxygenated organic molecules (HOM) O. Garmash https://doi.org/10.5281/zenodo.3543607
Short summary
Highly oxygenated organic molecules (HOMs) facilitate aerosol formation in the atmosphere. Using NO3− chemical ionization mass spectrometry we investigated HOM composition and yield in oxidation of aromatic compounds at different reactant concentrations, in the presence of NOx and seed aerosol. Higher OH concentrations increased HOM yield, suggesting multiple oxidation steps, and affected HOM composition, potentially explaining in part discrepancies in published secondary organic aerosol yields.
Highly oxygenated organic molecules (HOMs) facilitate aerosol formation in the atmosphere. Using...
