In this article, the free-ion energy-level schemes of the Pr3+, Nd3+, Pm3+, Sm3+, Dy3, Dy3+, Ho3+, Er3+, and Tm3+ aquo ions have been determined from their absorption spectra in dilute acid solution at 25°.Abstract:
The free‐ion energy‐level schemes of the Pr3+, Nd3+, Pm3+, Sm3+, Dy3+, Ho3+, Er3+, and Tm3+ aquo ions have been determined from their absorption spectra in dilute acid solution at 25°. Energy‐level assignments were made by comparison with crystal spectra, and on the basis of correlations between calculated and observed band intensities. For most of the ions, it was possible to identify several transitions giving rise to bands at energies as high as 45 000–50 000 cm−1. Sufficient numbers of assignments were made to justify inclusion of the effects of configuration interaction in the calculation of the energy‐level parameters. Variation of the electrostatic, spin–orbit coupling, and configuration‐interaction parameters across the lanthanide series is examined.read more

Spectral Intensities of the Trivalent Lanthanides and Actinides in Solution. II. Pm3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, and Ho3+
TL;DR: In this article, the experimentally determined band intensities in the solution absorption spectra of the trivalent lanthanides were correlated with a theoretical expression derived by Judd, and the spectra were measured in a single medium, dilute acid solution, and, in most cases, in the range ≈6000-50 000 cm−1.

G. H. Dieke,H. M. Crosswhite +1 more
TL;DR: The present status of our knowledge of the structure of the spectra of the rare earths is derived partly from experimental data of the emission spectra, which provides the energy level scheme in great detail but are difficult and laborious to analyze.
