ملخص

Energy transfer in nonreactive collisions of atom-diatomic molecules has been studied in three dimensions using Monte Carlo classical trajectories. Equations of motion, which predict the positions and momenta of the colliding particles after each step in the trajectory, have been integrated numerically by Runge-Kutta-Gill and Adams-Molton methods. The potential energy surfaces employed in the calculation, between the atom and each atom of the diatomic molecule, are Morse potentials plus an exponential repulsive term. Effects of the potential well-depth, initial energies (translational, rotational, and vibrational), and the masses of the colliding particles on energy transfer have been studied. The results show strong dependence of energy transfer type and quantity on these parameters. Dynamical analysis of the observations is given in order to get some understanding of the mechanism of energy transfer in nonreactive collisions.
