我们对取向的单壁碳纳米管进行了偏振拉曼光谱研究。这个测试系统使我们能够经验性地研究轴上偶极跃迁的共振拉曼散射是否遵循Cos2或Cos4马赛克扩散。我们在极图中观察到一种明显的co4依赖关系，这与传入和传出偶极跃迁的等价性是一致的。
We perform polarized Raman spectroscopy on aligned single-walled carbon nanotubes. This test system allows us to empirically address if resonant Raman scattering from on-axis dipole transitions follows a cos2or a cos4mosaic spread. We observe in the polar plots a clear cos4dependence, in agreement with the equivalency of incoming and outgoing dipole transitions.
