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 20200925, 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.
