Investigations of the optical spectra and EPR parameters for VO2+ ion in Na3C6H5O7ÃÆÃ¢â¬Å¡ÃâÃÂ·2H2O powders

The optical spectrum band positions and EPR parameters (g factors g//, g^ and hyperfine structure constants A// and A^) for VO2+ in Na3C6H5O7·2H2O powders are calculated from compl- ete diagonalization method and perturbation theory method. The theoretical results from both me- thods are in good agreement with the experimental values. The negative signs of hyperfine struc- ture constants A// and A^ for VO2+ in Na3C6H5O7·2H2O powder are suggested from the calcul- ations
