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 4I9/2 to 2P1/2 was performed in order to determine energy position of the 4I9/2 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.
