Abstract

Goals:; This experiment was done to photooxidize MPAN and capture NO3 with a-pinene, while observing secondary organic aerosol (SOA) formation through dry nucleation. MAE was added toward the end of the experiment to see if it enhanced SOA formation. Summary:; Addition of MAE didn't change the particle mass. Similar to 7/22 - we observed m/z 316, the pinene nitroxyhydroperoxide on CIMS, which showed that NO3 radical was liberated from the MPAN + OH reaction. This reaction produced a lot of SOA. Organization: Caltech Atmospheric Chamber; Lab Affiliation: California Institute of Technology, Pasadena, CA; Chamber: Near/Far Bag 2012-2015 (Tran) Experiment Category: Gas phase chemical reaction, Aerosol formation; Oxidant: Hydroxyl radical; Reactants: Methacrylolyl peroxynitrate (MPAN), ALPHA-PINENE, hydrogen peroxide, Methacrylic acid epoxide (MAE); Reaction Type: Photooxidation; Relative Humidity: 4; Temperature: 15; Pressure: 750 Torr
