ICARUS Chamber Experiment: Nguyen Group_20210115_2-methylbut-3-ene-1,2-diol/Methyl nitrite_Hydroxyl radical_Ammonium sulfate

Goals: Product and SOA formation study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) + OH, using wet (deliquesced) ammonium sulfate seeds at 50% RH. RO2 + NO pathway targeted.Summary: 1,2-DHI and CH3ONO were injected, AS solution was atomized, and lights were turned on to initiate photooxidation. Only 33% of lights were on for the first 7 minutes; all lights were turned on for the rest of photooxidation. A DNPH cartridge was collected after photooxidation to analyze for carbonyl content.Organization: Nguyen Group Lab Affiliation: UC Davis Chamber: Tran's big bag of airExperiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Hydroxyl radical Reactants: 2-methylbut-3-ene-1,2-diol, Methyl nitrite Reaction Type: Photooxidation Relative Humidity: 50 Temperature: 22 Seed Name: Ammonium sulfate Pressure: 755
