The Raman spectra of the natural end members of the garnet-group minerals, which include pyrope, almandine and spessarite of Fe-A1 garnet series and grossularite, andradite and uvarovite of Ca-Fe garnet series, have been studied. Measured Raman spectra of these minerals are reasonably and qualitatively assigned to the internal modes, translational and rotatory modes of SiO4 tetrahedra, as well as the translational motion of bivalent cations in the Xsite. The stretch and rotatory Alg modes for the Fe-Al garnet series show obvious Raman shifts as compared with those for the Ca-Fe garnet series, owing to the cations residing in the X site connected with SiO4 tetrahedra by sharing the two edges. The Raman shifts of all members within either of the series are attributed mainly to the properties of cations in the Xsite for the Fe-Al garnet series and in the Ysite for the Ca-Fe garnet series.

利用偏振喇曼光谱（PRS）和傅里叶变换红外光谱（FTIR）研究了三种不同成因电气石单晶的振动谱学特征。PRs研究表明电气石结构中三个阴离子团（即 [si6010] 12-、[B03]3-、[0H]一）的喇曼光谱在平行c轴方向（//Ne）比垂直c轴方向（//NC）敏锐。而且[0H]-喇曼光谱只在平行e轴的PRS中才观察到。不同成因电气石中 [0H]-占位不同。结合FTIR研究发现在伟晶型和热液型的电气石的隧道中还存在结晶水。这些发现不但在晶体化学、矿床成因方面有意义，而且为此类含水电气石的改性（如颜色、透明度、压电性及热电性等）提供了新思路。

氢在金刚石结构中是自陷的，可以稳定存在的自陷形式有成键氢，反键心氢，键心氢及四面体空隙氢四种模型，而且氢在其中的相对稳定程度依上述顺序渐次递减
