Properties of d-Electrons in Complex Salts. Part II ---Theory of the Optical Spectra with Particular Reference to the Effects of Spin-Orbit Interactions---

Abstract: A brief account of the ligand field theory, which has been developed in our previous papers and applied to the absorption spectra of the octahedral complex ions, is given. and some of the problems which were laid aside in those papers are treated. Especially, the effect of the spin-orbit interaction is studied on several particular complexes

Properties of d-Electrons in Complex Salts. Part III ---Detailed Studies of the Line Spectra---

Abstract: Experimental and theoretical studies previously done on the line spectra of transition metal ions in crysta's are summarized. Theoretical analyses free from any ambiguous quantities are attempted. The subjects discussed here are therefore mainly restricted to the qualitative nature of the Zeeman effects and optical anisotropies of the line spectra. Electric dipole transitions caused by small odd crystal fields and odd vibrations are discussed in detail, with special reference to vanadium and chromium corundum and chromium alums. In connection with the Zeeman effect of the absorption lines of chromium alums, vibronic problems of the excited doublet states of d 3 systems are also treated. Some magnetic dipole transitions in MnSiF.•6H,O crystals are quantita­ tively discussed. It is pointed out that their intensities are of comparable order of magnitude to those of the electric dipole transitions in the same crystal.
