In this study we conducted laboratory measurements to investigate the formation of gas-phase oxygenated organic molecules (OOMs) from six aromatic volatile organic compounds (VOCs). We provide a thorough analysis on the effects of precursor structure (substituents and ring numbers) on product distribution and highlight from a laboratory perspective that heavy (e.g., double-ring) aromatic VOCs are important in initial particle growth during secondary organic aerosol formation.
