使用的最新进展，在共振拉曼光谱研究孤立的碳纳米管和迄今为止从这些研究中取得的科学知识进行了讨论的背景下，推进碳纳米管为基础的技术。拉曼光谱的变化可用于探测和监测来自缺陷的引入和不同化学物质的附着的纳米管侧壁的结构改变。前一种效应可以通过分析无序诱导的拉曼模式来探测，后一种效应可以通过由于电荷转移效应在各种拉曼模式中观察到的上移/下移来探测。
The use of recent advances in resonance Raman spectroscopy studies on isolated carbon nanotubes and the scientific knowledge achieved so far from these studies is discussed in the context of advancing carbon nanotube-based technology. Changes in the Raman spectra can be used to probe and monitor structural modifications of the nanotube sidewalls that come from the introduction of defects and the attachment of different chemical species. The former effect can be probed through the analysis of the disorder-induced Raman modes and the latter through the upshifts/downshifts observed in the various Raman modes due to charge transfer effects.
