This paper updates and extends part of the previous database of critical
evaluations of the kinetics and photochemistry of gas-phase chemical
reactions of neutral species involved in atmospheric chemistry [J.
Phys. Chem. Ref. Data 9, 295 (1980); 11, 327 (1982); 13, 1259 (1984);
18, 881 (1989); 21, 1125 (1992); 26, 521 (1997); 26, 1329 (1997)]. The
present evaluation is limited to the organic family of atmospherically
important reactions. The work has been carried out by the authors under
the auspices of the IUPAC
Subcommittee on Gas Phase Kinetic Data Evaluation for Atmospheric Chemistry.
Data sheets have been prepared for 171 thermal and photochemical reactions,
containing summaries of the available experimental data with notes giving
details of the experimental procedures.
For each thermal reaction, a preferred value of the rate coefficient
at 298 �K is given, together with a temperature dependence where possible.
The selection of the preferred value is discussed, and estimates of
the accuracies of the rate coefficients and temperature coefficients
have been made for each reaction.
For each photochemical reaction, the data sheets list the preferred
values of the photoabsorption cross-sections and the quantum yields
of the photochemical reactions, together with comments on how they were
The data sheets are intended to provide the basic physical chemical
data needed as input for calculations that model atmospheric chemistry.
A table summarizing the preferred rate data is provided, together with
an Appendix listing the available values of enthalpies of formation
of the reactant and product species.
