title: Raman spectroscopic study of the antimonate mineral roméite.
abstract: Raman spectroscopy has been sued to study the antimony containing mineral roméite Ca(2)Sb(2)O(6)(OH,F,O) from three different origins. Roméite is a calcium antimonate mineral of the pyrochlore group. An intense Raman band at approximately 518 cm(-1) for roméite is assigned to the SbO nu(1) symmetric stretching mode and the band at 466 cm(-1) to the SbO nu(3) antisymmetric stretching mode. The Raman band at 303 cm(-1) is attributed to the OSbO bending mode. Some variation in band positions is observed and is attributed to the variation in composition between the three mineral samples.
