Raman scattering study of Ξ΄-BiB3O6 crystal
The total set of polarized Raman spectra have been obtained at room temperature, and an assignment of observed modes based on the lattice dynamics simulation and polarization selection rules is proposed. An LO-TO splitting of A1 Raman bands have been observed
Anisotropic crystal of the Ξ΄-BiB3O6 investigated by vibrational spectroscopy
The vibrational spectroscopy has been applied to investigate the structure the BiB3O6 (BIBO) crystal. Based on the experimental results, the total set of phonons mode of the polarized Raman spectra was proposed. To verify the obtained experimental data have been performed theoretical calculation in software package LADY

Polarized Raman spectroscopy of delta-BiB3O6 at 7β350 K
BiB3O6 crystal has been characterized by Raman spectroscopy. Polarized low-frequency spectra have been obtained. Temperature measurements have been carried out in range 7β350 K. Raman spectra have been numerically simulated with lady software package. The results of experiment confirmed the contribution of the Bi3+ ions and BO4 groups in nonlinear optical properties of BiB3O6. The studied crystal is a promising medium for up- and down-Raman laser-frequency converters

Vibrational spectra of NdF3 crystal
The vibrational spectroscopy investigation of phase transitions in NdF3 crystal is reported. Spectra were obtained in temperature range from 300 to 10 K. It has been shown that, down to 10K, the orthorhombic tysonite structure of NdF3 trifluoride remains stable
