Abstract

The polarized spectra of Raman scattering (RS) in the region 20 - 1000 cm^-1 and infrared absorption (IR) spectra at 5 K and 300 K were studied. The detail examination of polarized and low temperature absorption spectra in the region of Nd³⁺ transition from ground state ⁴I_9/2 to ²P_1/2 was performed in order to determine energy position of the ⁴I_9/2 Stark levels. An analysis and comparison of the RS and IR absorption spectra at room temperature allows us to assert that the NdGaO₃ structure at this temperature region belongs to the Pbnm space group.
