Author(s)
Vladimir L. Orkin, Gregory A. Poskrebyshev, Michael J. Kurylo III
The rate constants for the reactions of OH radicals with fully fluorinated alkenes containing different number of –CF3 groups next to olefinic carbon, CF2=CF2, CF2=CFCF3, CF3CF=CFCF3, (CF3)2C=CFC2F5 were measured using the flash photolysis resonance

Determination of Atmospheric Lifetimes Via the Measurement of OH Radical Kinetics

December 1, 2003
Author(s)
Michael J. Kurylo III, Vladimir L. Orkin
The reaction with hydroxyl radicals in the troposphere is the main atmospheric removal process for the majority of gases of industrial and natural origin. Their residence time in the atmosphere can be estimated based on the reactivity towards OH and some
