| 摘 要： | 测量了单层纳米碳管的一级、二级拉曼光谱.在40—3300cm-1范围内观测到18条一级拉曼谱线和7条二级拉曼谱线,理论所预言的谱线几乎全被观测到，谱峰位置和理论值符合得很好.通过和理论值的对照，对这些谱线作了初步标定.所观测到的单层纳米碳管的拉曼激活振动模数目及二级拉曼谱线条数都是迄今最多的.关键词：

| Abstract: | The first and second-order Raman spectra were measured for single-wall carbon nanotubes (SWNTs). Eighteen first-order Raman spectral lines and seven second-order Raman spectral lines were observed. Spectral lines predicted by theory were almost fully detected. Positions of the spectral lines observed are well coincident with theoretical values. The number of Raman active phonon modes and the second-order Raman spectral lines for high-purity SWNTs observed is the biggest up to date. |
