NONADIABATIC EFFECTS IN THE STATISTICAL ADIABATIC CHANNEL MODEL - THE ATOM+DIATOM CASE

Nonadiabatic coupling between exit adiabatic channel states is considered for an atom + diatom collision complex. Nonadiabatic transition probabilities are estimated on the basis of a sequential two-state correlation diagram which qualitatively reproduces adiabatic potential barriers arising from an anisotropic interaction in a system "point charge-linear dipole rotor." The implication of nonadiabatic interaction in changing statistical adiabatic channel predictions for product distribution functions are briefly discussed.
