[Study on the Raman spectra of baotite]

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(B1g), 460 and 488 cm-1 (Eg) and 622 cm-1 (A1g). 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.
