Abstract : The probability of making transitions between specifically known molecular states in collisional processes has been investigated theoretically. Fully quantum mechanical close-coupled calculations of electronic-vibrational-translational energy exchange for model atom-diatomic potentials have been performed. The process of ion-pair formation was investigated in this work. Symmetric charge exchnage in diatomic ion-diatomic molecule collisions was also studied. Nonadiabatic collisions were studied by quasi-classical and quantum perturbation methods as well. Finally, scaling laws for collisions of atomic Rydberg states with atoms and molecules have been developed. (Author)
