Abstract : It has been shown that the partial g-sum rule can be a useful tool for the interpretation of impurity-ion optical spectra. Several theoretical and experimental results have been discussed wherein the accuracy of the sum rule is illustrated. Recent optical Zeeman studies of triply-ionized neodymium and erbium have been compared with theoretical predictions. Discussion has shown how some of the difficulties of optical Zeeman spectroscopy may be circumvented through the use of special, excited-state EPR techniques. A double resonance system has been described with which experiments are presently being conducted on the new laser host, LiYF4.
