Name: Jimenez Lab_20160823_1-Hexanol/1-octanol/1-Nonanol/1-DECANOL/1-DODECANOL/Methyl nitrite/nitric oxide_Hydroxyl radical_Di-octyl sebacate_2.9_ug/m3_#1
Date: 2016-08-23

Organization
Jimenez Lab

Chamber
1-White (1W)

Experiment Set
Gas-aerosol-wall partitioning kinetics from Krechmer EST 2017 (DOS seed aerosol, various concentrations)

Goals
Fast burst photooxidation of alkanols (high-NOx). Gas-aerosol-wall partitioning kinetics. Determine accommodation coefficient (alpha) and effective volatility under differing liquid organic seed aerosol concentrations.

Summary
Alkanols, Methyl nitrite, NO, and DOS seed added to chamber, UV lights turned on for 10 sec, multifunctional products formed, and measured with nitrate CIMS
