ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20140824_ISOPRENE/CYCLOHEXANE/sulfur dioxide_Ozone_No Seed_Dry

Goals: This experiment was performed to study the competition between the reactions of the smallest stabilized Criegee intermediate (SCI) CH2OO with water (or water dimer) and SO2

Summary: At ~3% RH and 15 ppb SO2, there was a bit more sulfate particle formation as seen by the AMS, but still fairly low. While SCI+H2O products are still abundant from CIMS

Experiment Category: Gas phase chemical reaction Oxidant: Ozone Reactants: ISOPRENE, CYCLOHEXANE, sulfur dioxide Reaction Type: Dark oxidation Relative Humidity: 3 Temperature: 24 Pressure: 750 Torr
