On the Absorption Spectra of Complex Ions IV. The Effect of the Spin-orbit Interaction and the Field of Lower Symmetry on <i>d</i> electrons in Cubic Field

Abstract

It is shown that the matrix elements of the crystalline field of lower symmetry than cubic and of the spin-orbit interaction for d -electrons in octahedral complex ions can be easily evaluated by the method of tensor operators, and the tables necessary to evaluate these elements by this method are given. It is also pointed out that the effective Hamiltonian which plays the same role as the spin Hamiltonian for the non-degenerate states can be constructed for the degenerate orbital states and will be useful for the analysis of line spectra of these complexes.
