ICARUS Chamber Experiment: Nguyen Group_20190806_ALPHA-PINENE/OZONE/10102-44-0/hydrogen peroxide_Nitrate radical_Ammonium sulfate

Goals: To quantify the nitrooxy-hydroperoxide yield and the SOA yield from nighttime RO2+HO2-dominated NO3-initiated chemistry of a-pinene by adding H2O2 + ozone + NO2 to the chamber. Part of a series of varying initial reactant concentrations slightly to target different chemical pathways. This one likely got high RO2+RO2 and RO2+HO2 chemistry Summary: H2O2, NO2, and O3 were injected in the chamber and allowed to equilibrate, forming NO3 (and some N2O5) and probably HO2. Ammonium sulfate seed particles were injected. Then a-pinene was injected and decayed by simultaneous reaction with ozone and NO3. Gas phase was monitored by CF3O- CIMS and particle formation by SMPS. Organization: Nguyen Group Lab Affiliation: UC Davis Chamber: Tran's big bag of air Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Nitrate radical Reactants: ALPHA-PINENE, OZONE, 10102-44-0, hydrogen peroxide Reaction Type: Dark oxidation Relative Humidity: 5 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755 Torr
