Title:

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


Description:

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.
