Rate Constants for the Reactions of Methylvinyl Ketone, Methacrolein, Methacrylic Acid and Acrylic Acid with Ozone A contribution to subproject CMD Antje Kolloff, Peter Neeb, Stephan Koch and Geert K. Moortgat Max-Planck-Institutfur Chemie, Division of Atmospheric Chemistry, P.O. Box 3060, D-55020 Mainz, Germany Introduction In recent years rate constants for a large number of hydrocarbons and oxygenated hydrocarbons with OH, Os and NOs have been reported in the literature (Atkinson, 1997). These data provide valuable information to assess the tropospheric lifetimes and the relative importance of the various degradation pathways of these compounds. Since isoprene is the most important emitted non- methan-hydrocarbon (Guenther et al., 1995), investigations have focused on the tropospheric degradation of isoprene and its oxidation products. While rate constants for the various degradation
