- •
Phonon modes of LiBaB9O15 crystal was determined by polarized Raman spectroscopy.
- •
7A1g+6Eg was observed out of 11A1g+ 25Eg vibrations predicted by the Group Theory.
- •
A tentative mode assignment is given based on other BO3- and BO4- based compounds.
- •
Fewer modes observed than predicted are analyzed.
