Abstract
The electron paramagnetic resonance spectra of Cu2+ doped KHCO3 single crys tals were studied at room temperature. The results indicate a substitutiona l entrance of the Cu2+ ions in place of the magnetically inequivalent K+ si tes. The charge compensation is supposed to be fulfilled by proton vacancie s. The hyperfine lines were well resolved and the Cu-65 hyperfine coupling tensors were also found. The ground state of Cu2+ indicates the dominance o f the d(x2-y2) orbital and, therefore, elongation of the polyhedron, simila r to a lengthened octahedron.
