摘要	The EPR parameters (g factors g(parallel to), g(perpendicular to), and hyperfine structure constants A(parallel to), A(perpendicular to)) of Ti3+ ion at the sixfold coordinated Al3+ site with trigonal symmetry in beryl crystal are calculated by the third-order perturbation formulas of 3d(1) ions in a trigonal octahedron. In the calculations, the crystal-field parameters are obtained by the superposition model, and the impurity-induced local lattice relaxation (which is similar to that found for Fe3+ in beryl) is considered. The calculated EPR parameters (and also the optical spectra) are in reasonable agreement with the experimental values.
