A theoretical method for studying the optical spectra and electron paramagnetic resonance (EPR) parameters of Yb 3+ ions in SrWO 4 crystal is presented. Using the crystal‐field theory, the formulas relating the optical spectra and EPR parameters are derived. Based on the theoretical formulas, the 14×14 full energy matrices for 4f 13 configuration ions in a D 2d point symmetry are constructed. By diagonalizing the full energy matrices, the optical spectra and EPR data of Yb 3+ in SrWO 4 crystal have been investigated. The theoretical results are in good agreement with the experimental values. Furthermore, the crystal‐field parameters for SrWO 4 have been determined in this work.
