The kinetic and product studies conducted during the first year of this intended two-year experimental program have provided new information which (1) allows the rate constants for the O3 reactions with numerous alkenes to be placed on a firmer basis than was previously the case (and these data have already been included in a critical review and evaluation of O3 reaction kinetics), and (2) provides new and quantitative information concerning the production of OH radicals from O3-alkene reactions. Although not discussed in the report, gas samples were collected from the O3-alkene reactions in the presence of cyclohexane to scavenge OH radicals and analyzed by DGA, Inc. for carbonyls and organic acids. These data will serve as important input to future detailed chemical mechanisms for use in airshed computer models for photochemical air pollution, prior to their testing against environmental chamber data.
