Abstract
Symmetry adaptation techniques developed in the first papers
of this series are applied to intensity calculations for one- and
two-photon transitions between crystalline or molecular states
arising from a configuration nlN in a symmetry G. To illustrate
the techniques, we begin with one-photon magnetic-dipole transitions.
Then, we give a detailed treatment of the second-order mechanisms for two-photon electric-dipole transitions; the case of configuration 4f6 in symmetry C4v serves as an illustration. We also give indications of the passage from second-order to higher-order mechanisms. Finally, some general symmetry considerations for one-photon electric-dipole transitions are briefly investigated.
