用拉曼散射和红外吸收研究了机械磨石墨中的氢键态。拉曼散射光谱中没有C-H振动信号，而红外吸收光谱中有明显的C-H振动信号。随着磨矿时间的延长，C-H - 3的贡献略有增加。这一结果标志着在氢气气氛下首次用实验方法测定了机械磨石墨中的氢态。
The hydrogen binding state in the mechanically milled graphite has been investigated by Raman scattering and infrared absorption. There is no C–H vibration signal in Raman scattering spectra, while, a C–H vibration signal has been clearly observed by infrared absorption. The dominant hydrogen configuration is C–H 2 and the contribution of C–H 3 slightly increases for a longer milling time. This result indicates the first experimental determination of the hydrogen state in the mechanically milled graphite under hydrogen gas atmosphere.
