ICARUS Chamber Experiment: Nguyen Group_20190808_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+HO2, with some background RO2+RO2 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.
