Formation, Clustering, and Atmospheric Impact of Clusterable Organic Compounds

Atmospheric aerosol particles have a critical impact on Earth’s radiative balance and human health. Oxygenated organic molecules play an important role in the formation and growth of aerosol particles. To contribute to initial steps of particle formation, a compound must either condense from the gas to the particle phase or undergo cluster-phase proton-transfer or other chemical reaction. I define a clusterable organic compound (COC) to be an oxygenated organic molecule which can participate stable cluster formation under atmospheric conditions. Due to the limited knowledge of the formation, structures, and properties of COCs, the exact mechanisms for the formation of aerosol particles remain puzzling. In this presentation, I will show our recent findings of COC formation and clustering mechanisms as well as discuss why accurate quantum chemical studies are needed to understand molecule–climate integration.
