Abstract Raman scattering spectra of perovskite‐like (NH 4 ) 3 WO 3 F 3 oxyfluoride are studied in the 70–3600 cm –1 frequency range and the 93–323 K temperature range including the transition point from orientationally disordered cubic phase into the lower symmetry one. Internal vibrations of ammon...
