โฆ Synopsis
Values of average energy transferred, (AC). and average energy loss, (h),, per collision were calculated from classical trajectories for collinear A*+ M collisions in which A2 is highly vibrationally excited. Results were compared with those from the singleencounter impulsive collision model, from three-dimensional trajectories for atom-polyatom collisions and from experiments which studied collisions of polyatoms with atoms and with other polyatoms. A number of similarities were noted, in particular,' wide ranges of temperature Z'wherein (A+ and (As)4 vary slowly with T.

An analytical method of calculating the energy transfer in classical, collinear atom-diatom collisions, based on the use of power-series expansions in the parameter w7 (o is the frequency of the molecular vibrations, 7 is an effective coihsion time) is presented.

Cross sections and rate constants for the inelastic collision, OH(A2Z+,v=I,j=15) + Ar ~ OH(A2 r.+,v=0,]=20) + Ar, have been calculated in the infinite-order sudden (IOS) and distorted-wave (DW) approximations. The results agree well with experiment.
A study of the vibration-translation energy transfer in atom-diatom collinear collisions is made. Using an algebraic approach developed by Gazdy and Micha, the time evolution operator of the linearly driven parametric oscillator (LDPO) is obtained, and used to transform the cubic part of the interac
