| Abstract: | The Raman spectrum of lithium Diborate (Li2B2O7:LBO) has been determined. Thedifferent internal modes have been analyzed. It is proved that the Raman spectra consist of BO3triangular and BO4 tetrahedron internal modes. Because of the effect of delocalization of electron.the LBO crystal has nonliner characters, but from the B-O streching vibration, it can be seen thatits nonliner characters is not strong. |
