在较宽的温度范围内测量了碳纳米管上的电子顺磁共振（EPR），氧化管后共振消失。就石墨特性和引入变形势来描述管状结构的模型来讨论结果。由于载流子绕管作圆周运动，它会在磁场中产生持续的环形电流。讨论了自旋角动量相互作用，试图解释纯化碳纳米管中缺乏 EPR。
Electron paramagnetic resonance (EPR) on carbon nanotubes was measured in a wide range of temperatures, the resonance disappeared after oxidizing the tubes. The results are discussed in terms of graphite properties and a model introducing a deformation potential to describe tubular structure. It leads to persistent ring currents in the magnetic field due to the carriers circular motion around a tube. A spin–angular-momentum interaction is discussed in an attempt to explain the lack of EPR in purified carbon nanotubes.
