Kinetics Of Atmospheric Reactions Of Biogenic Volatile Organic Compounds: Measurement Of The Rate Constant Ofthujone + Cl· At 296 K And Calculation Ofthe Equilibrium Constant For The Ho2ch2ch2o2· H2o Complex, Marie Coy Killian
Theses and Dissertations
Biogenic volatile organic compounds (VOCs) react with Cl and OH radicals and the resulting radicals combine with oxygen to form peroxy radicals RO2. Organic peroxy radicals can then react with NO to form NO2, a precursor of tropospheric ozone. The work presented here explored the initial reaction between Cl and thujone, a VOC emitted by Great Basin sagebrush. The rate constant for the reaction of thujone + Cl at 296 K was measured with the method of relative rates with FTIR for detection of reactants. LEDs were used to photolyze Cl2 to generate Cl in the reaction cell. Thujone was …
