通过对双壁碳纳米管径向呼吸模式的拉曼散射截面的分析，我们可以确定内管的光学跃迁。发现拉曼谱聚集成具有相似共振行为的种类。簇的最低组分对应于硫酸钠包裹的高压一氧化碳生长管。每个星团代表不同外管中的一个特定内管，星团的每个成员代表一对定义明确的内管和外管。一个簇中的组件数量随着内径的减小而增加，最高可达14个分布在30厘米1上。这表明直径变化很大
The analysis of the Raman scattering cross section of the radial breathing modes of double-wall carbon nanotubes allowed us to determine the optical transitions of the inner tubes. The Raman lines are found to cluster into species with similar resonance behavior. The lowest components of the clusters correspond well to sodium sodecyl sulfate wrapped high pressure carbon monoxide grown tubes. Each cluster represents one particular inner tube inside different outer tubes and each member of the clusters represents one well-defined pair of inner and outer tubes. The number of components in one cluster increases with the decreasing inner tube diameter and can be as high as 14 spread over 30 cm 1 . This suggests a lot of variation in the diameter
