Abstract Spectral intensities of six Nd3+ nitrogen-oxygen donor and sulfur donor complexes have been reported. The experimental data have been correlated with the theoretical values calculated using Judd's relation, and Judd'sT λ parameters are reported. The mean error is small, showing the applicability of Judd's relation. A comparison with other Nd3+ complexes shows that, in general, the transitions are weaker for the complexes under study. The intensity of the hypersensitive transition andT 2 parameter follow the order of the ligands: oxygen donor〉nitrogen-oxygen donor〉nitrogen donor〉sulfur donor〉aquo ion, suggesting that the involvement of the Nd3+ f-orbitals is greatest in the case of O-donor complexes. The other two parametersT 4 andT 6 are nearly constant. The nature of the model required by the theory is discussed.
