Electron capture, rate comparison with

Theory was compared with experimental results on ion—dipolar charge transfer [60, 61] and proton transfer [62, 63] reactions, and was found to predict very satisfactorily the rate coefficients of proton transfer reactions which are considered to proceed by a capture mechanism. The energy dependence of the proton transfer was also correctly represented by the theory. As to the charge transfer reactions, the comparison is difficult because the observed rate coefficients are considerably larger than the capture limit. This is explained by the contribution of a long range electron-jump mechanism to the rate coefficients. Even in this case, however, the trend of the dipole effect is predicted correctly by the theory.
