ICARUS Chamber Experiment: 2014 FIXCIT Study_20140116_ALPHA-PINENE/Methyl nitrite_Hydroxyl radical_No Seed_Alpha-pinene + OH "slow chemistry", dry, 40C, no seeds

Goals: Investigate "slow" (isomerization-favoring) OH chemistry of alpha-pinene Summary: Timeline (UTC, hours): 00:00, Instruments (NO; CF3O-; GTHOS; OHR; AMS; PTRMS) start sampling the bag 00:30, Instruments stopped sampling; added CH3ONO to the bag with 5 SLM zero air 00:35, Added alpha-pinene with 6 SLM zero air in 50degC water bath 01:22, Stopped alpha-pinene addition 01:30, Certain instruments started sampling (CF3O- CIMS; GTHOS; NO). GTHOS and NO off bag overnight 02:05, 2 UV bulbs on (~1% lights) 16:05, Instruments started sampling on bag; AMS saw nucleation overnight; O3 instrument reads 10 ppbv 16:30, Lights off 17:34, Lights on (20%) 18:15, Lights on (100%) 19:37, Lights off 20:20, Add 2 minutes of NO flow to kill O3/HO2 22:45, Stopped sampling; start flushing Organization: 2014 FIXCIT Study Lab Affiliation: California Institute of Technology Chamber: Seinfeld chambers Experiment Category: Gas phase chemical reaction Oxidant: Hydroxyl radical Reactants: ALPHA-PINENE, Methyl nitrite Reaction Type: Photooxidation Relative Humidity: 5 Temperature: 40 Pressure: 750 Torr
