摘要

在这项理论工作中，我们利用结合键极化率模型的谱矩方法研究了氢化单壁碳纳米管(SWNTs)的拉曼光谱。分析了碳-氢键对碳纳米管拉曼模式的影响。加氢的百分比从1%到5%进行了研究。研究发现，碳-氢键在2880 ~ 2900 cm-1范围内具有明显的拉伸模式，且碳纳米管的径向呼吸模式(RBM)受氢化的影响大于g波段。随着加氢浓度的增加，还预测了d波段新的拉曼活性模式的重新出现。

Vibrational study of hydrogenated Single Wall Carbon Nanotubes

In this theoretical work, we study the Raman spectra of hydrogenated single walled carbon nanotubes (SWNTs) using the spectral moments method (SMM) coupled to the bond polarizability model. The effect of the C-H bond on the Raman modes of carbon nanotube are analyzed. Percentage of hydrogenation from 1% to 5%, are investigated. We found that the stretching modes of C-H bonds are clearly observed in the 2880-2900 cm-1 range and the Radial Breathing Mode (RBM) of SWNTs is more affected by the hydrogenated than the G-band. The reappearance of new Raman active modes in the D-band is also predicted as we increase the hydrogenation concentration.
