Classical, diatomic molecule, kinetic theory cross sections. II. Collision dynamics

The dynamics of collisions between nonvibrating diatomic molecules is discussed in terms of a system of collision coordinates introduced earlier in the development of classical expressions for the generalized or kinetic theory cross sections. The expressions developed earlier are then rewritten in terms of precollision values of functions introduced in the discussion of the dynamics, which may be evaluated either through a perturbation solution of the equations or a stepwise numerical solution.
