We report polarized Raman spectra for a set of heavy-metal multi-component fluoride glasses, containing the fluorides of hafnium, zirconium, barium, lanthanum and thorium. All the glasses have a dominant peak in their VV spectrum in the vicinity of 580 cm-1 with a corresponding deep minimum in their depolarization spectrum. The spectra are relatively depolarized from near 200 cm-1 to 400 cm-1.
