摘要：

The electron paramagnetic resonance spectra of Cu2+ doped KHCO3 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 Cu-65 hyperfine coupling tensors were also found. The ground state of Cu2+ indicates the dominance of the d(x2-y2) orbital and, therefore, elongation of the polyhedron, similar to a lengthened octahedron.
