Theoretical Study on the Reaction of <i>p</i> ‐Cymene with Ozone

Volatile organic compounds (VOCs) react with atmospheric OH, NO 3 , and O to form having lower volatility, contributing secondary aerosols (SOAs). Consequently, characterizing the reaction intermediate for this is essential modeling formation of SOAs. Herein, we proposed a mechanism ozonolysis p ‐cymene calculated energies intermediates generated during each step by density functional theory (DFT). According our calculation, high‐energy biradicals were produced in ‐cymene, which plays an important role SOAs, thereby affecting climate air quality.
