摘要: 在加工单晶宝石的过程中，晶体定向有着非常重要的作用。傅里叶变换红外光谱和激光拉曼光谱定向测试宝石虽然得到的结果不一定准确，但是可以作为辅助证据对传统结晶学定向进行验证。通过对顽火辉石样品的切片进行定向的红外光谱、激光拉曼光谱测试与对比分析，探讨了利用红外光谱、拉曼光谱进行晶体定向的可能性，获得了可以利用红外光谱的水峰在3 400～3 600 cm-1范围内的形状、强度及位置、拉曼光谱中的1 009～1 020 cm-1处拉曼峰形态、强度总体峰数量、荧光背景等要素对顽火辉石晶体进行初步定向的认识。Abstract: Crystal orientation plays an important role in gemstone cutting. The orientation of crystal tested by FTIR spectroscopy and Raman spectroscopy could be used as supporting evidences to judge the traditional crystallography orientation. In this paper, the authors collected and tested the oriented infrared spectrum, Raman spectrum of 9 sections of enstatites, in order to explore the function of FTIR and Raman scattering in oriented spectroscopy. Finally, the results showed that both the shape, intensity and location of IR spectrum with OH bands at 3 400～3 600 cm-1, and the shape, intensity, number of bands, fluorescent background of Raman spectrum at 1 009～1 020 cm-1, could be used to give an orientation of single enstatite crystal.
