利用旋转电池技术记录了石墨烯炭黑的拉曼光谱。1360、1580和2700 cm−1处的散射角依赖性被报道，这些数据表明1360 cm−1线与非平面微观结构畸变有关。1360 (D)和1580 cm−1(G)波段强度比的激发频率依赖关系被解释为共振（振动）相互作用。这种依赖性主要是1360 cm−1线强度增加的结果。无序相关谱线(D)显示出从1378 cm−1（457.9 nm Ar+）到1330 cm−1（647.1 nm Kr+）的显著的激发相关位移。“石墨”(G)线位置对激励频率的变化不太敏感。从因子群C6v4和层位对称C3v两个方面讨论了光谱特征。此外，还考虑了局部类烯烃结构在结构畸变区可能起的作用。
The Raman spectrum of Graphon carbon black has been recorded using rotating cell techniques. Angular dependence of scattering at 1360, 1580 and 2700 cm−1are reported and these data suggest that the 1360 cm−1line is associated with non-planar microstructure distortions. The excitation frequency dependence of the intensity ratio of the bands at 1360 (D) and 1580 cm−1(G) is interpreted in terms of resonance (vibronic) interaction. This dependence is primarily the result of an increase in the intensity of the 1360 cm−1line. The disorder-associated line (D) exhibits a significant excitation-dependent shift from 1378 cmi−1(457.9 nm Ar+) to 1330 cm−1(647.1 nm Kr+). The “graphite” (G) line position is less sensitive to changes in excitation frequency. The spectral features are discussed in terms of factor group,C6v4, and layer site symmetry,C3v. Also the possible role of localized alkene-like structure in zones of structural distortion is considered.
