Abstract
Raman spectra of ferritungstite are interpreted on the basis of model calculations. The presence of two broad vibrational bands in the spectral range 600–1000 cm−1 is explained through the combination of two factors. Mainly, two principle bands in the spectral ranges 600–750 and 850–1000 cm−1 are characteristic of the pyrochlore-type structure attained by ferritungstite and correspond to symmetric and asymmetric stretching of the W-O bonds, respectively. Also, broadening of the Raman lines results from structural disorder caused by the presence of iron atoms.
