Satisfactory Prediction

The spin-lattice relaxation time of dilute potassium ferricyanide was measured as a function of the orientation of the static magnetic field in three orthogonal planes at 9.4 GHz and 1.75 °K.A calculation of the spin-phonon Hamiltonian applicable to the case of three Kramer doublets degenerate with respect to the cubic component of the crystalline bond is given. The theory was applied to the ferricyanide on the basis of Van Vleck's point-charge model.Despite the fact that the ferricyanide complex is known to be considerably covalent, it is found that the theory gives a satisfactory prediction of the observed angular dependence.
