	Article:	RAMAN SPECTROSCOPY OF Pb(V_1-xM_x)O₃ PEROVSKITE COMPOUNDS. Authors: N. LEOPOLD.


	Abstract: The perovskite oxide Pb(V_1-xM_x)O₃ (M=Ti,Fe and x=0.00;0.25) was synthesised by solid state reaction under high pressure – high temperature conditions. Using Raman scattering spectroscopy, single phase formation of PVO (x=0.00) with the shift of phonon modes was confirmed. Raman spectroscopy was used as a local probe sensitive to even subtle changes of symmetry after the partial substitution of V with x=0.25 Ti and Fe. Keywords: PbVO₃, high pressure - high temperature synthesis, Raman spectroscopy.
