High-lying quantum states of molecule are apt to be populated by translational-to internal energy transfer in the collisions with atom, which usually becomes more significant with the increase of collision energy. However, in the charge exchange reaction Ar+ + NO -> Ar + NO+, the products NO+ prefer a dominant population at the lowest triplet state a(3)Sigma(+), in particular, in the higher energy collisions; the higher states b(3)II and w(3)Delta of NO+ are accessed only at the lower collision energies. Such a striking collision-energy dependence is attributed to two distinctly different processes: the former is controlled with an energetically resonant charge-transfer mechanism; while the latter experiences an intermediate complex (Ar-NO)(+) which permits a more efficient translational-to-internal energy transfer.
