本文报道了未经处理和离子注入的高取向热解石墨（HOPG）的斯托克斯和反斯托克斯拉曼光谱。对于所有的拉曼谱带，在不同的温度下观察到明显的频移。反常的拉曼现象（阿普）表明，出现在斯托克斯和反斯托克斯侧的一些模式对于HOPG具有不同的频率。实验结果表明，阿普与石墨的拉曼谱带的激发波长（\ensurmath {\lambda}）依赖性密切相关。根据温度效应和阿普，我们对HOPG的一些模式进行了指认和验证，并预测了一些新的结果。
The Stokes and anti-Stokes Raman spectra of the pristine and ion-implanted highly oriented pyrolytic graphite (HOPG) are reported. For all Raman bands, noticeable frequency shifts are observed in the different temperature of samples. The anomalous Raman phenomenon (ARP) indicates that some modes occurring on the Stokes and anti-Stokes sides have different frequencies for HOPG. The data suggest that the ARP is closely related with the excitation wavelength (\ensuremath{\lambda}) dependence of Raman bands of the graphite. According to the temperature effect and the ARP, we assign and verify some modes of HOPG, and predict some new results.
