Rate coefficients ⟨σv⟩ for Mn + H (upper) and Ti + H (lower) collision processes at 6000 K, plotted for various asymptotic energy differences between initial and final molecular states, ΔE. The data shown is for endothermic processes only, i.e., excitation and ion-pair production. Legend labels are given for the initial state of Mn or Ti involved in the transition, and processes leading to a final state that is ionic are circled.
