Abstract

<p>Goals:<br/> 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 was predominantly to collect a filter to analyze the chemical content of pinene ozonolysis SOA by offline HRMS.</p> <p>Summary:<br/> H2O2 and O3 were injected in the chamber and allowed to equilibrate. Then a-pinene was injected and decayed by reaction with ozone. The first pinene injection (100 ppb) didn't produce enough SOA for a good filter to analyze by HRMS, so more pinene was injected (150 ppb) over two periods until SOA produced was greater than 200 ug/m^3. Gas phase was monitored by CF3O- CIMS and particle formation by SMPS. After all injections, a filter was collected for offline HRMS analysis.</p> <p>Organization: Nguyen Group<br/> Lab Affiliation: UC Davis<br/> Chamber: Tran's big bag of air</p> <p>Experiment Category: Gas phase chemical reaction, Aerosol formation<br/> Oxidant: Ozone<br/> Reactants: ALPHA-PINENE, OZONE, hydrogen peroxide<br/> Reaction Type: Dark oxidation<br/> Relative Humidity: 5<br/> Temperature: 22<br/> Seed Name: N/A<br/> Pressure: 755 Torr</p>
