Evaluated Kinetic and Photochemical Data for Atmospheric Chemistry: Supplement IV. IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry

This paper updates and extends previous critical evaluations of the kinetics and of gas phase of neutral species involved in atomosphere chemistry [J. Phys. Chem. Ref. Data 9, 295 (1980); 11, 327 (1982); 13, 1259 (1984); 18, 881 (1989)]. The work has been carried out by the authors under the auspices of the IUPAC Subcommittee on Gas Phase Kinetic Data Evaluation for Data sheets have been prepared for 489 thermal and containing summaries of the available experimental data with notes giving details of the experimental procedures. For each a preferred value of the rate coefficient at 298 K is given together with a dependence where possible. The selection of the preferred value is discussed, and estimates of the accuracies of the rate coefficients and coefficients have been made for each The data sheets are intended to provide the basic data needed as input for calculations which model A table summarizing the preferred rate data is provided, together with an appendix listing the available data on of the reactant and product species.
