摘要	Two distinctive theoretical methods, the complete diagonalization (of energy matrix) method (CDM) and the perturbation theory method (PTM), are employed to calculate the optical band positions and EPR g factors g(parallel to), g(perpendicular to) for the tetragonal Cu2+ centers in trigonal ZnCO3 crystal. The results from the two methods coincide and are also in good agreement with the experimental values. So both the CDM and PTM are adequate for the investigations of optical and EPR data for d(9) ions in crystals. The tetragonal distortion due to the static Jahn-Teller effect for the tetragonal Cu2+. centers in trigonal Zn2+ site of ZnCO3 is also acquired from the calculations. The results are discussed.
