Özet

We studied the electron paramagnetic resonance (EPR) spectra of VO2+ ions in ammonium hydrogen tartrate (AHT) single crystals at room temperature. We determined the spin Hamiltonian parameters and the molecular bonding coefficients of the complex both in theoretical and experimental ways. The results indicate that the vanadium ion forms a tetragonally compressed octahedron and has a double bond with one of the oxygens in the axial position. This is the reason why the paramagnetic centre in the host crystal is axially symmetric as in most of the vanadyl ion-containing complexes.
