Abstract
The theory of energy transfer in molecular collisions is of importance for the understanding of a great variety of physical problems.(1–7) In many of these problems we are interested in determining probabilities of energy transfer between the translational motion and one or more of the internal motions of the molecules. There has been much work done in recent years on the calculation of vibrational transition probabilities and inelastic scattering cross sections in which vibrational and/or rotational states are excited. Such collisions are a characteristic process in a simple molecular gas in the temperature range from 100° to 5000°K. Electronic transitions during collision will take place to a significant extent only at higher temperatures. For a gas in thermal equilibrium, individual molecules are constantly gaining or losing energy through collisions, but the total energy is unchanged. If conditions of equilibrium are suddenly changed, the gas finds itself seeking a new state of equilibrium; the rate of adjustment is governed directly by the collision efficiency, which measures the amount of energy either gained or lost per collision. At large separations, the colliding molecules attract slightly so their electron cloud overlapping is not important. However, as they approach each other to close range, where the overlapping of electron clouds is appreciable, repulsive forces are set up.
