石墨边缘面的拉曼光谱与切割基底面的拉曼光谱不同，1355 cm−1和1620 cm−1波段清晰可见。边缘平面的这些光谱特征被解释为由于抛光造成的结构缺陷。本文系统地研究了各种方法制备的边缘平面的拉曼光谱。结果表明，观测到的边缘平面的光谱特征主要是由于石墨面不可避免地存在于边缘的不连续。结果表明，石墨材料的拉曼光谱既可以评价石墨化程度，也可以评价石墨面取向。这些发现被应用于石墨纤维径向非均质性的表征和碳碳（C/C）复合材料的界面分析。
The Raman spectrum of the graphite edge plane is different from that of the cleaved basal plane because the 1355 cm−1and 1620 cm−1bands are clearly observed. These spectral features of the edge plane have been interpreted to be due to the structural imperfection caused by polishing. In the present work, the Raman spectra of the edge planes prepared by various methods were systematically studied. As a result, it was concluded that the observed spectral features of an edge plane were mainly due to the discontinuity of graphite planes that inevitably exists at the edge. It was also demonstrated that either the degree of graphitization or the orientation of graphite planes can be evaluated by the Raman spectra of graphite materials. These findings were applied to the characterization of the radial heterogeneity of a graphite fiber and the interfacial analysis of a carbon-carbon (C/C) composite.
