TLDR
In this article, the generalized crystal field theory of Finkelstein and Van Vleck is augmented by the introduction of spin-orbit coupling and an attempt is made to account for both the spin-allowed and spin-forbidden dn, (n = 2, 8), spectral transitions of Ni(II) and V(III) complexes.About:

Optical Spectra of Ni2+, Co2+, and Cu2+ in Tetrahedral Sites in Crystals
Abstract: The polarized absorption spectra of Ni2+ and Co2+ in crystals of ZnO, ZnS, and CdS; Ni2+ in crystals of Cs2ZnCl4 and Cs2ZnBr4; and Cu2+ in ZnO have been measured at 4°K, 77°K, and room temperature. The spectra have been interpreted by the use of crystal field theory for the states of the (3d)n configuration acted on by a potential of predominately Td symmetry. Certain details of the spectra are accounted for by smaller contributions from fields of lower symmetry, notably a C3v potential contribution for the transition metal ions in ZnO. Crystal field, electrostatic repulsion, and spin‐orbit parameters have been obtained for all these cases. An empirical correlation between the electrostatic repulsion parameter, B, for the ions in the crystals and the ligand polarizibility has been obtained. Although the configuration mixing between the states of the configurations (3d)n and (3d)n—1 (4p) has been found to give a negligible contribution to the calculated relative energies of the levels, it does partially ex...

The Nephelauxetic Series
TL;DR: In this article, the authors define a two-dimensional classification of octahedral complexes, according to two variables : Δ in the spectrochemical series and β in the nephelauxetic series, i.e., the ratio between the value of a representative parameter of interelectronic repulsion.

Electronic Spectra of Molecules and Ions in Crystals Part II. Spectra of Ions in Crystals: Part II. Spectra of Ions in Crystals
TL;DR: In this paper, the problem of finding a zeroth-order approximation in terms of which the spectra may be understood qualitatively is presented, and that may serve as a starting point for calculation.

A semi-empirical energy-level diagram for octahedral cobalt(II) complexes
TL;DR: In this paper, a method of calculation for the parameters Dq and B from the ligand-field spectra of octahedral cobalt(II) compounds is introduced, which considers the lowering of the 4T1g (F) state by spin-orbit splitting.

On the Absorption Spectra of Complex Ions II
Yukito Tanabe,Satoru Sugano +1 more
TL;DR: In this paper, the authors solved the energy levels which are important in the absorption spectra of the normal complex ions, leaving the crystalline field strength as a parameter The values of B and C (Racah's parameters) there needed are determined from the observed spectras of free ions or in some cases by extrapolation The f -values of the transitions which connect energy levels calculated are estimated and compared with the observed intensities.
