Paper Abstract

A general method for the calculation of matrix elements of multipolar terms of spherical top molecules is presented. It uses the tensorial algebra techniques that have been developed for these types of molecules, and is particularly suitable for computer implementation. Multipolar transition moments calculated in the lowest vibrational states of 12CH4, are given in graphical form showing their dependences with respect to the internal dynamics of the molecule. It is then shown how this type of calculation can be naturally inserted in semi classical line broadening and shifting calculations.
