The local structure, two optical band positions and three electronic spin resonance parameters for Cu^{2+} centers at the tetragonally-distorted octahedral sites in ZnO-Bi_2O_3-B_2O_3-CuO glasses are calculated from the high-order perturbation method based on the two-spin-orbit-parameter model, where the contributions from both the spin-orbit coupling parameters of central d^{n} ion and ligand ion are included. The theoretical results are in good agreement with the experimental values. The calculations show that the high-order perturbation method based on the two-spin-orbit-parameter model is effective in the explanations of optical spectra, electronic spin resonance parameters and local distortion structure for d^{9} ions in glasses.
