The Raman Spectrum of alpha-Zirconium Fluoride and Implications for the Bridging Modes of Fluorozirconate Glass
Abstract
The previously undetermined Raman spectrum of alpha-ZrF4 is reported and used to interpret the Raman spectra of binary barium fluorozirconate glasses. Under the assumption of separability of the motions of different types of bridging fluoride ions, it is shown that the edge, or doubly bridging, fluoride structure exhibits a characteristic band in the alpha-ZrF4 crystal spectrum which is also identifiable in the glass spectra, in contrast to previous interpretations. New assignments are proposed for the main peaks in the fluorozirconate glass spectra, and an approximate mathematical treatment is used to explain the observed frequencies of the two types of bridging Zr-F bonds.
