拉曼光谱是任何碳系统的标准表征技术。本文综述了无定形碳、纳米结构碳、类金刚石和纳米金刚石的拉曼光谱。我们展示了如何使用共振拉曼光谱来确定碳膜的结构和组成与氮和没有。测量的光谱随激发能量的变化而变化。通过可见光和紫外光激发测量，可以推导出G峰色散，并与关键参数，如密度，sp（3）含量，弹性常数和化学成分相关。然后，我们讨论了在纳米金刚石中经常观察到的1150和1480 cm（-1）处的峰的归属。我们回顾了共振拉曼，同位素取代和退火实验，导致这些峰的归属反式聚乙炔。
Raman spectroscopy is a standard characterization technique for any carbon system. Here we review the Raman spectra of amorphous, nanostructured, diamondlike carbon and nanodiamond. We show how to use resonant Raman spectroscopy to determine structure and composition of carbon films with and without nitrogen. The measured spectra change with varying excitation energy. By visible and ultraviolet excitation measurements, the G peak dispersion can be derived and correlated with key parameters, such as density, sp(3) content, elastic constants and chemical composition. We then discuss the assignment of the peaks at 1150 and 1480 cm(-1) often observed in nanodiamond. We review the resonant Raman, isotope substitution and annealing experiments, which lead to the assignment of these peaks to trans-polyacetylene.
