Chrysoberyl AI:BeO4 is isomorphous with olivine (MgFe)2SIO4, and belongs to orthorhombic system with space group P?m?-D2h16. Vibrational properties of olivine and Mg2SiO4 have been extensively investigated for the sake of geophysics and mineralogy, while the vibrational properties of Al2BeO4, was less studied. It is found
