Exact and vibrational sudden approximation (VSA) transition probabilities for He+ HIZ, Be&, BeBr, and CO2 at 0.5 to 3.0 eV are calculated and compared. The agreement between the VSA and the exact results for the excitation of the symmetric stretch is excellent for HI2 (even for large changes in the
Calculations for non-adiabatic atom-molecule collisions at low energies frequently make use of a sudden approximation vis-avis the molecule rotation. The present work investigates the effect on vibronic excitation and charge-transfer processes of freeing the rotation of the molecule during the colli
