It also provides a quick and convenient summary of the contents of a save tape. Pressure broadening in vibrational bands is often well approximated by ignoring vibrational coupling, in which case molecular scattering calculations for rotational excitation can be done separately for each vibrational level.
Current code is limited to full close coupling cases only.
Senftleben-Beenakker effect cross sections. It converts saved S-matrices to generalized phenomenological cross sections defined by Fitz, Kouri, Liu, McCourt, Evans, and Hoffman, J. Chem.
