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, hrs): 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 min of NO flow to kill O3/HO2 22:45,Stopped sampling; start flushing
