Abstract

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. This experiment serves as the "no-NO2" control for the experiment on 20200928, using the same parameters but without NO2, to examine just the ozonolysis chemistry. Summary: H2O2 and O3 were injected in the chamber and allowed to equilibrate. Ammonium sulfate seed particles were injected. Then a-pinene was injected and decayed by reaction with ozone. 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: Ozone Reactants: ALPHA-PINENE, OZONE, hydrogen peroxide Reaction Type: Dark oxidation Relative Humidity: 5 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755 Torr
