利用分子光谱谱带位移、谱带强度、谱带形态等的变化,可以初步对晶体作结晶学定向.普通辉石结构OH红外光谱3组谱带值,垂直c轴方向相对于平行c轴的谱带各不相同:第一组谱带值,3 629～3 633cm~(-1)谱带红移到3 601～3 616 cm~(-1);第二组谱带值3 514～3 543 cm~(-1)同样有红移现象;第三组3 460～3 465 cm~(-1)的谱带值相反则有蓝移现象.相对强度上,两个方向上第一组的谱带强度相当;第二组、第三组谱带强度平行方向明显强于垂直方向.形态上则差别不大.拉曼谱垂直方向谱带强度普遍强于平行方向,谱带位置与形态基本不变.结构OH不同结晶方向的谱图性质可以反映一定的地质构造环境.

Crystal can be crystallographically oriented by rnolecular spectrum with the change in band shift, band intensity, and band shape. The three groups of band shift of angite are different between vertical to c-axis and parallel to c-axis: the first peak value 3 629-3 633 red shifts to 3 601-3 616; the same as the second peak value 3 514-3 543; on the contrary, the third peak value 3 460-3 465 is blue shill The intensity of the first band is equivalent in two directions, while the second and the third parallel to c-axis are much stronger than the vertical The wave shape is not quite different. The intensity of the Raman spectra vertical to c-axis is stronger than that parallel to c-axis in general, while the band shift and the shape show little difference. It was indicated that the geological tectonic environment can be reflected by the spectra of structural hydroxide with different crystal directions.
