Rapid Photolysis of Gaseous Organic Nitrates Formed from Hydroxyl and Nitrate Radical Oxidation of α‑Pinene and β‑Pinene.

ABSTRACT: Photolysis of gaseous organic nitrates is crucial for understanding the formation and fate of air pollutants such as nitrogen oxides (NO _x ) and ozone (O₃). Monoterpenes are prevalent biogenic volatile organic compounds (VOCs), greatly contributing to the formation of organic nitrates; however, there is currently a lack of experimental constraints on the photolysis chemistry of monoterpene organic nitrates. Here, we investigated the photolysis of monoterpene organic nitrates via novel dual chamber experiments, in which a large suite of organic nitrates was formed from hydroxyl and nitrate radical oxidation of α-pinene and β-pinene in one chamber and were introduced into another chamber to study photolysis. We directly measured their photolysis rates with chemic
