The calculations of EPR parameters (g factors g(parallel to), g(perpendicular to) and zero-field splitting D) related to the impurity structures have been made from the high-order perturbation formulas for Cr3+ ions in trigonal KSc(MoO4)(2), RbSc(MoO4)(2) and RbSc(MoO4)(2) crystals. It is found that the MO6 octahedra in these crystals change from the trigonal elongation in the pure crystals to the trigonal compression in the impurity centers. The results are discussed.
