Raman spectra were obtained from PtO, Pt 5 O 6 , Pt 3 O 4 , α‐PtO 2 , β‐PtO 2 , M x Na y Pt 3 O 4 (M = Co, Ni), PtCoO 2 and MPt 3 O 6 (M = Mn, Co, Cd). An enumeration of the allowed Raman modes is made for all of these oxides except Pt 5 O 6 , for which the structure is unknown. Polarization measurements allow symmetry species assignments to be made for the lines from α‐PtO 2 and PtCoO 2 , and a likely assignment of the lines from β‐PtO 2 is made by analogy with rutile‐structured materials with the rutile structure.
