Goals:
Product study on 2-methylbut-3-ene-1,2-diol (1,2-DHI) + OH, trying to target the RO2+RO2 pathway with really high 1,2-DHI loading but the RO2+HO2 pathway still likely dominated.

Summary:
1,2-DHI and H2O2 were injected and lights were turned on to initiate photooxidation. A DNPH cartridge was collected towards the end of the experiment to analyze for carbonyl content. Some new particle formation observed, possibly from dimers!
