A treatment based on Badger's rule is used to estimate symmetric stretching frequencies νs of the nonbridging fluorides of various ZrFn groups in the presence of divalent and monovalent countercations.New vibrational spectra of MgZrF6, Ba2ZrF8, and β-BaZr2F10 are presented and incorporated into the method.The factors affecting νs are outlined and discussed in detail.Compilations of estimated frequencies are used to deduce the probable local structure around Zr ions in binary barium fluorozirconate glasses and in fluorozirconate melts containing lithium and sodium ions.It is concluded that the results of Raman spectroscopy indicate the presence of seven- and eight-coordinate Zr in some barium fluorozirconate glasses.
