金刚石中杂质相的研究一直倍受关注但大多集中在B、N两种杂质的研究上而对于氢在其中的赋存状态研究则刚刚开始。从振动谱学flR、R㈣n] 的角度对氢在金刚石中的一种赋存状态——成键氢进行的研究表明成键氢在金刚石中可以以碳氢键、H,及OH键的形式存在。

【期刊论文】Raman Spectroscopy of Garnet-group Minerals
彭明生, PENG MNGSHENG, H.K. MAO, LI DIEN
CHINESE JOURNAL OF GEOCHEMISTRY 1994, 13 (2): 179~183,-0001,():

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.

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
