ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20140722_Methacrylolyl peroxynitrate (MPAN) / ALPHA-PINENE / hydrogen peroxide_Hydroxyl radical_No Seed_Dry
d789197
Goals: This experiment was done to photooxidize MPAN and capture NO3 with a-pinene, while observing secondary organic aerosol (SOA) formation through dry nucleation. Summary: 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 Reaction Type: Photooxidation Relative Humidity: 4 Temperature: 15 Pressure: 750 Torr
