Abstract The electron paramagnetic resonance spectra of Cu2+ doped Na2HAsO4 ·7H2O single crystals were studied at room temperature. The results indicate the substitutional entrance of Cu2+ in two magnetically inequivalent Na+ sites. Charge compensation is supposed to be fulfilled by proton vacancies. The spin Hamiltonian parameters were determined. The ground state for Cu2+ seems to indicate the dominance of the dz² orbital and therefore a compression of the distorted octahedron along its C4v axis.

The electron paramagnetic resonance spectra of Cu2+ doped KHC03 single crystals were studied at room temperature. The results indicate a substitutional entrance of the Cu2+ ions in place of the magnetically inequivalent K+ sites. The charge compensation is supposed to be fulfilled by proton vacancies. The hyperfine lines were well resolved and the 65Cu hyperfine coupling tensors were also found. The ground state of Cu2+ indicates the dominance of the dx2-y2 orbital and, therefore, elongation of the polyhedron, similar to a lengthened octahedron.

Abstract Electron Paramagnetic Resonance (EPR) studies have been carried out on the vanadyl (VO2) ion doped in single crystals of ZnTiF6 • 6H2O. The spectra indicate the presence of one set of eight lines characteristic of only one occupation site. The V-O bond orientation is along one of the three Zn-H2O bond directions in the trigonally distorted [Zn(H2O)6] octahedra. This behaviour is unlike that reported for vanadyl ion substituting for the M(H2O)6 sites in the Tutton salts, alums and AlCl3 • 6H2O. The Spin-Hamiltonian and bonding parameters for the [VO(H2O)5] complex have been evaluated. The hyperfine linewidths are 0.8 mT at 300 K and 77 K. No proton superhyperfine structure was observed at both these temperatures.
