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.
拉曼光谱已被用于研究来自三个不同产地的含锑矿物罗镁石 Ca(2)Sb(2)O(6)(OH,F,O)。罗镁石是烧绿石族的一种钙锑矿。罗镁石在约 518 cm(-1)处的强拉曼带归因于 SbO nu(1)对称伸缩模式，在 466 cm(-1)处的带归因于 SbO nu(3)反对称伸缩模式。303 cm(-1)处的拉曼带归因于 OSbO 弯曲模式。观察到带位置的一些变化，这归因于三个矿物样品之间的组成变化。
