Summary
With the increasing resolution of new experimental techniques, it has become possible to overcome some of the congestion in Rydberg spectra and to analyse the rotational structure. This article has reviewed the algebra of some of the different coupling cases involving the angular momenta of a Rydberg electron with the electronic and rotational angular momenta of the core. The characteristic behaviour of most Rydberg states corresponds to Hund’s case (d) or (e) for the Rydberg electron, and the use of the asymptotic approximations given in Appendix B provides a qualitative physical picture of the interactions in the different coupling situations.
