Abstract:

The classical, semiclassical, and quantum mechanical procedures used for calculating the vibrational energy transferred in collisions of diatomic molecules are explored in detail. The validities of the approximations used in each method are discussed. Theoretical transition probabilities are calculated and compared for an exponential repulsive interaction between a harmonic oscillator and an incident particle using a linear collision model. Results obtained using potentials which include the effects of anharmonicity and attractive forces are discussed. Treatments of vibrational-vibrational energy transfer in diatomic-diatomic collisions are presented. After introducing thermal averaging procedures and three dimensional calculations, a comparison is made between the theoretical transition probabilities and experimental results. Author
