包头矿的拉曼光谱

Study on the Raman Spectra of Baotite

本文报道了我国发现的一种含大量Ba、Ti和Nb的硅酸盐类新矿物 包头矿的拉曼光谱特征 ,着重讨论了拉曼光谱带的归属问题 ,确定了包头矿中钛氧八面体和硅氧四面体的主要拉曼光谱的振动频率 。

The Raman spectra of baotite have been studies by a type of SPEX-1403 0.85 double laser Raman spectrometer. In this work we report Raman spectra of baotite. The preliminary conclusions based on author's work are drawn as follow:the Raman vibration frequency of two texture type has been observed in baotite. One is the vibration frequency of the Ti-O octahedron,they are 192 and 322 cm(-1) (B-1g), 460 and 488 cm(-1) (E-g) and 622 cm(-1) (A(1g)). An other is the vibration frequency of Si-O tetrahedron, they are 980 and 1 122 cm(-1). At the same time,some physical properties and chemical compositions of baotite are also discussed in this paper.
