Paramagnetic Resonance in some Complex Cyanides of the Iron Group II. Theory

摘要: The theory of Stevens for covalent XY6 complexes is developed the cases d3 and d5 with low symmetry, compared magnetic resonance results preceding paper. effect coupling to doublet states on spin Hamiltonian constants found be small that quartet states, although latter are probably further removed energetically. In it shown relation between g-values susceptibility does not depend orientation principal axes g tensor relative complex; values K3Fe(CN)6 calculated from earlier experimental determinations, value spin-orbit being adjusted give best fit. observed hyperfine K4Mn(CN)63H2O theoretical expressions can explained reasonable parameters. orbital g-factor k 0.87 ferricyanide 0.74 manganocyanide. An appendix discusses conditions under which terms symmetry appear in Hamiltonian, they may have spectrum.
