By means of the diagonalization of the complete energy matrix of 3d(2)/d(8) ions in trigonal symmetry and in consideration of the covalency reduction effect, the optical and EPR spectra of V3+ ions in C(NH2)(3)Al(SO4)(2)center dot 6H(2)O crystal are calculated. The results are in agreement with the observed values. The difficulty about the too-large spin-orbit coupling parameter in the explanation of EPR parameters from the Abragam and Pryce model is removed. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
