Abstract
The EPR spectra of VO2+ ions in ammonium oxalate monohydrate, [(NH4)(2)C2O4 . H2O], single crystals have been studied at room temperature and at 113 K in mutually three perpendicular planes. The spin Hamiltonian parameters ar e determined using a numerical technique together with a trial and error pr ocedure to resolve the single crystal spectra. The parallel and perpendicul ar components of axially symmetric g and hyperfine tensors for VO2+ ion in ammonium oxalate monohydrate single crystal are determined, and the results are discussed.
