We use polarized Raman spectroscopy to obtain the room temperature phonon modes of LiBaB 9 O 15 single crystal, that crystallizes in a trigonal structure belonging to the space group R 3¯ c (D 3 d 6) with two molecules per primitive cell (Z B= 2). The structure of the LiBaB 9 O 15 crystal consists of a three-dimensional borate framework, formed by two BO 3 triangles and one BO 4 tetrahedra. Since BO 3 and BO 4 units share the oxygen atoms, we can not obtain a correlation scheme where their internal modes are distributed in terms of the irreducible representations of the D 3d factor group. The only modes that can unambiguously be assigned are the ν 3 (BO 4) with A 1g symmetry at 983 cm− 1 and the ν 1 (BO 3) with E g symmetry at 932 cm− 1. We observed 7A 1g+ 6E g out of 11A 1g+ 25E g vibrations predicted by the Group Theory.
