| Abstract | The vibrational spectra and structure of isolated [WO4]2− anions in molten alkali, alkaline-earth, rare-earth, Pb, Bi, Zn, Sc, and Cd tungstates are studied by high-temperature Raman spectroscopy. The degenerate modes of the [WO4]2− anion in K-Gd tungstate melts are found to be split, which is interpreted in terms of the symmetry of the cation environment of the [WO4]2− anion in the melts. The frequency of the fully symmetric stretching mode (ν1) of the [WO4]2− group in molten tungstates is examined in relation to the polarizing power P and electronegativity γ of the cation. The origin of the nonmonotonic variation of ν1 with P and γ for the tungstate melts studied is discussed. |
