Charge transfer was found to occur by two distinct mechanisms: (1) a simple electron‐jump mechanism which preserves the quasirectilinear trajectories of the colliding species and which selectively produces H2 + in the vibrational state most nearly resonant with the reactant ion, and (2) an intimate‐collision mechanism which results in large‐angle scattering and which produces H2 + in a broad range of vibrational states.Article10.1063/1.435181openAccess
