Abstract
A study was conducted to evaluate the OH rate constant measurement protocol developed by researchers at the University of California at Riverside. The protocol, which is a relative rate method, was used to measure room temperature OH rate constants for a series of low molecular weight, high volatility compounds that consists of examples from alkane, alkene, aromatic, oxygen-containing compound, and chlorinated compound classes. OH rate constants were determined for 21 compounds. The rate constants were compared with literature values. The OH rate constants obtained are in good agreement with literature values for all classes of compounds except for chlorinated compounds where rate constants had not been previously determined for most of the compounds studied. The protocol can be used to determine OH rate constants as low as 0.5 x 10 to the minus 12 power cu.cm./molecule-sec. The results obtained for chlorinated compounds suggest that Cl reactions can interfere with the OH rate constant determination.
