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...

Spin‐Orbit Interaction in Aromatic Molecules
TL;DR: In this paper, the matrix elements of spin-orbit interaction were obtained for polyatomic molecules using M.O. wave functions, taking account of configurational interaction, and the results were then applied to the calculation of singlet-triplet transition probabilities in aromatic compounds.

Covalent bonding and magnetic properties of transition metal ions
J Owen,J H M Thornley +1 more
TL;DR: In this article, the wave functions of the magnetic electrons are considered first, the covalency being taken into account by admixing ligand s and p orbits into the central ion d orbits.
