Abstract: The EPR spectra for VO<superscript>2+</superscript> in CaO-Al<subscript>2</subscript>O<subscript>3</subscript>-SiO<subscript>2</subscript> system are calculated using complete diagonalization method (CDM) and perturbation theory method (PTM). The calculated results are in good agreement with the observed values. By comparing the calculated results by CDM and PTM in a wide range of crystal field parameters, the validity of the PTM formulas has been studied. It is shown that, the PTM formulas are reasonable and reliable in a wide range of CF parameters. [ABSTRACT FROM AUTHOR]
