ICARUS Chamber Experiment: Nguyen Group_20210204_2-methylbut-3-ene-1,2-diol/Methyl nitrite_Hydroxyl radical_Ammonium sulfate

Goals: Product & SOA formation study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) + OH, seeded (ammonium sulfate), dry, trying to get the best conditions possible for any isomerization/autooxidation to occur (including high temperature, low OH / light)Summary: The chamber was heated to 35 degree C and all but two lights were removed from the chamber (~3% of maximum light flux). 1,2-DHI and CH3ONO were injected, AS was atomized, and the bag was allowed to mix and equilibrate, after which the lights were turned on and left on overnight (greater than 24 hours). The CIMS was ran out of reagent gas, so signals were pretty wonky after 6:00 am on the second day.Organization: Nguyen Group Lab Affiliation: UC Davis Chamber: Tran's big bag of airExperiment Category: Gas phase chemical reaction Oxidant: Hydroxyl radical Reactants: 2-methylbut-3-ene-1,2-diol, Methyl nitrite Reaction Type: Photooxidation Relative Humidity: 5 Temperature: 35 Seed Name: Ammonium sulfate Pressure: 755
