Electron paramagnetic resonance parameters of V2+ ions in both Cd2+ sites of CsCdCl3 crystal.

From the perturbation formulas based on a two-spin-orbit-parameter model, the electron paramagnetic resonance (EPR) zero-field splitting (D), g-factors (g(parallel to), g(perpendicular to)) and hyperfine structure constants (A(parallel to), A(perpendicular to)) for V2+ in Cd2+ (I) and Cd2+ (II) sites of CsCdCl3 crystal at room and liquid nitrogen temperatures are calculated. From the calculations, the signs of zero-field splittings and hyperfine structure constants are determined and so all of the EPR parameters are explained reasonably on the basis of the structure data of lattice.
