Collision spectroscopy

Even now that computers are available for solving collision problems, two-state models of the strong nonadiabatic coupling still play an important part. This is substantiated by the development of collision spectroscopy, which successfully interprets the complicated differential scattering in terms of these models. In such cases the main object of the theory of nonadiabatic processes consists in the explicit formulation of the 2 X 2 scattering matrix as a function of the parameters of the accepted model. 

We believe that for a considerable time the uncertainty that arises in using models will be still less than that due to errors in potentials. Only in exceptional cases when exact reconstruction of potentials from scattering data is attempted, as is the case in collision spectroscopy, will more refined treatment of nonadiabatic coupling be needed.
