Title:

ICARUS Chamber Experiment: Nguyen Group_20190425_ALPHA-PINENE/hydrogen peroxide/OZONE/10102-44-0_Nitrate radical_Ammonium sulfate


Description:

Goals:
To assess the feasibility of accessing nighttime HO2-dominated chemistry of a-pinene by adding H2O2 + ozone + NO2 to the chamber. Overall goals will include quantifying the nitrooxy-hydroperoxide yield and the SOA yield from this reaction pathway

Summary:
H2O2, NO2, and O3 were injected in the chamber and allowed to equilibrate, forming NO3 (and some N2O5) and probably HO2. 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. A filter was collected for later offline analysis.
