Highly oxygenated organic molecules
WebJan 12, 2024 · Rapidly and widely formed, highly oxygenated organic molecules (HOMs) 8,9,10,11 have been identified to be critical for NPF and growth, and therefore for CCN formation 12,13,14,15. WebMar 30, 2024 · Recently, it was discovered that some VOCs form highly oxygenated organic molecules (HOMs) via a process called autoxidation ( Crounse et al. , 2013). These molecules are estimated to explain a large fraction of SOA formation due to their low volatilities ( Ehn et al. , 2014; Kirkby et al. , 2016).
