ICARUS Chamber Experiment: Ziemann_20160218_pyrocatechol/nitric oxide/methyl nitrite_Hydroxyl radical_Dioctyl Sebacate_Catechol + OH/NOx_highConc

Goals:
Determine the SOA yield, products and molar yield of SOA products for the reaction of catechol with OH in the presence of NOx at high concentrations.

Summary:
Reaction occurred in 5 minutes, was conducted at 50% lights, reacting 560 ppb of catechol. SOA mass yield was 110%, 4-nitrocatechol yield was 33%.
