Theory of thermal unimolecular reactions at low pressures. II. Strong collision rate constants. Applications

Troe, J.·1977·The Journal of Chemical Physics

Abstract

Theoretical expressions for the strong collision rate constants of thermal unimolecular reactions at low pressures k0sc are discussed. The rate constant is split up into various factors: a basic expression for a simplified harmonic oscillator model, a factor accounting for anharmonicity effects, a factor accounting for the energy dependence of the density of states, an overall rotation factor accounting for the effects of centrifugal barriers, and an internal rotation factor accounting for the barriers of hindered rotors. Simplified and easily applicable expressions for these factors are derived. The theory is applied in detail to many practical examples. The comparison with experimental results demonstrates the large importance of the weak collision effects which have been treated in part I of this article. Empirical values for the weak collision efficiencies βc are derived and compared with predicted values.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
