State-dependent rate constants for the reaction $\text{H}+{\text{H}}_2^{+}\left(v=0,j=0\right)\to {\text{H}}^{+}+{\text{H}}_2$. In the bottom panel, CT, RCT and the total sum are presented. In the middle and top panels, the pure CT and RCT process are shown, respectively, showing the final state distribution of ${\text{H}}_2^{+}\left(v^{\prime }\right)$ vibrational states. The dotted curve represents the Arrhenius fit to the total rate constant. The point in the lower panel corresponds to the experimental measurement by Karpas et al. (1979).
