| Abstract: | A new decoupling scheme for atom — rigid-rotor scattering based on Jacob and Wick's helicity formalism is suggested and found to be satisfactory for a wide range of systems of chemical interest. The number of coupled equations which needs to be solved simultaneously is greatly reduced. Conditions for the validity of this approximation are explored. Very accurate results are obtained for the opacity functions of the individual transitions. |
