Abstract: Recent atmospheric studies have mentioned that gas phase Criegee intermediates (CIs), R1R2COO, may act as oxidizing agents to initiate aerosol formation.1 These CIs are formed in the troposphere by ozonolysis of unsaturated hydrocarbons emitted from plants. For simple CIs we have studied the decay process including the reaction with water vapor as well as thermal decomposition.2–5 From a combination of theoretical simulation and experimental detection, we provide our understanding toward the lifetime of CIs in atmospheric conditions.
