摘要	By using the bond length dependence of covalency reduction factor obtained from the high pressure spectroscopy of ruby (Al2O3:Cr3+), the pressure-induced shifts of (2)E-(4)A(2) transition line for Cr3+ ions in both sites (mirror site and inverse site) of chrysoberyl BeAl2O4:Cr3+ are calculated from the distinctive compressibilities of metal-ligand bond for Cr3+ ions in the two sites. The results are in reasonable agreement with the observed values. It suggests that the large difference of the pressure-induced shifts of (2)E-(4)A(2) transition line between the Cr3+ ions at the mirror sites and the inverse sites of chrysoberyl is due mainly to the different average bond compressibility.
