β¦ Synopsis
The results of classical trajectory calculations for rigid rotator p-Ha-p-Ha collisions are presented. Several trajectory methodologies are compared_ Over the energy range for which quanta1 results are available classical-quanta1 comparisons are poor.

Classical trajectory calculations have been performed for the O + 0 2 collision at different initial relative translational energies. Several modes of collision have been identified by the close examination of the plot of the number of trajectories on collision duration (r)-the number of exchanges o
