Laboratory reaction rate constant measurements for negative ion – atom interchange reactions, negative ion charge transfer reactions, and negative ion three-body association reactions of aeronomic interest are reviewed and the available data tabulated. The present experimental techniques in use are briefly summarized. Most of the rate constants have been measured only at 300 °K; in a few cases data is available at energies [Formula: see text] as well as at 300 °K, so that an indication of the energy dependence of the rate constants is available.
