摘要
The EPR and optical spectra for VO2+ in C3H7NO2 powders are calculated from complete diagonalization method and perturbation theory method, respectively. The calculated results are in good agreement with observed values. The negative signs of hyperfine structure constants A(parallel to) and A(perpendicular to) for VO2+ in C3H7NO2 powders are also suggested from the calculations.
