研究了锑矿水镁矿NaSbO_3的拉曼光谱，并与矿物的结构进行了关联。617cmSBO1和660cmSBO1处的两个尖峰属于−对称伸缩模式。产生两个对称伸缩振动的原因取决于SBO单元之间的结合。617 cm−1处的带被指定为通过Sb键合，660 cm−1处的带被指定为通过氧键合。508 cm−-1处的低强度带归因于SbO的反对称伸缩振动。在5 0 3、5 2 6和5 78 cm−1处观察到低强度谱带。在2 0 4、2 30、30 7和315 cm−1处观察到的尖锐拉曼谱带归属于Osbo弯曲模。拉曼光谱可以更好地了解矿物水镁石的分子结构。
Raman spectra of antimonate mineral brizziite NaSbO3 were studied and related to the structure of the mineral. Two sharp bands at 617 and 660 cm−1 are attributed to the SbO symmetric stretching mode. The reason for two symmetric stretching vibrations depends upon the bonding of the SbO units. The band at 617 cm−1 is assigned to bonding through the Sb and 660 cm−1 to bonding through the oxygen. The low intensity band at 508 cm−1is ascribed to the SbO antisymmetric stretching vibration. Low intensity bands were found at 503, 526 and 578 cm−1. Sharp Raman bands observed at 204, 230, 307 and 315 cm−1 are assigned to OSbO bending modes. Raman spectroscopy enables a better understanding of the molecular structure of the mineral brizziite.
