| Abstract: | The pressure-induced shifts of optical spectral bands 4T2 and 2E for the preferential Cr3+-centered octahedron for Cr3+ at the Sc3+ site of the LiSc (WO 4)2 crystal have been calculated from crystal-field theory. From the calculation, the local linear compressibility d ln R/d p≈?3.3×10?4 kbar?1 for the Cr3+ center in a LiSc (WO 4)2 crystal is obtained. The result is discussed. |
