摘　　要：采用Nicolet 550型傅立叶变换红外光谱仪对六块同一方向的碧玺薄片进行红外光谱测试,测试结果表明同一方向碧玺的红外吸收光谱特征基本相同。其红外光谱分析表明碧玺中存在一定含量的水,另外,其本征峰Si-O振动及(BO3)3-振动均显示较强的吸收,其中Si-O振动相对来说尤其强,表明在垂直于碧玺C轴方向Si-O振动很强。Six tourmalines with the same direction have been tested by Nicolet 550 transform infrared spectra （FTIR）, and the results have shown that the IR absorbing spectral characteristics of the samples are nearly the same. The IR spectra also indicate a certain content of water contained in tourmaline. Additionally, stronger absorption have presented in intrinsic peaks of Si-O and （BO3）3vibration, especially the Si-O vibration, which indicates that the Si-O vibration perpendicular to C-axis of tourmaline is very strong.
