Reactions of ground-state oxygen atoms, O(3P), with alkenes are of both fundamental and practical importance. O(3P) reactions are necessary to accurately model the early stages of smog formation in urban areas and are often important in atmospheric pressure chamber studies of alkene reactions with OH. O(3p) reactions are also of central importance in combustion chemistry and serve as prototype systems for the addition reactions to the C=C bond. Although a substantial body of kinetic data exits for O atom reactions with a variety of alkenes, only limited information is available for haloalkenes. Most of these studies have been indirect measurements of the rate coefficients by the relative rate method.  The present work was undertaken in order to augment the existing scant supply of kinetic  information about the (O3P) haloalkene reactions.
