Аннотация: Raman spectra of a polycrystalline sample of the perovskite-like oxyfluoride (NH4)(3)TiOF5 are measured in the frequency region 100-3600 cm(-1) at temperatures ranging from 91 to 370 K under hydrostatic pressures of up to 9 GPa, which include the range of the phase transition from the orientationally disordered cubic phase to the lПоказать полностьюow-symmetry phase. Anomalies in the spectral parameters due to the phase transition are revealed in the range of vibrations of TiOF5 octahedral groups.
