The applicability of Raman spectroscopy to characterize disordered and heterogeneous carbonaceous materials (CM) is discussed, by considering both natural and synthetic CM. First, different analytical mismatches during the measurement are discussed and technical indications are provided in order to eliminate them. Second, the accuracy and relevance of the different parameters obtained by the decomposition of spectra by conventional fitting procedure, is reviewed. Lastly, a new Raman technique (Raman area mode microspectroscopy) giving an homogeneous repartition of power within a large laser beam is presented, this technique being powerful to study strongly heterogeneous CM and/or photosensitive samples.
本文通过考虑天然和合成的含碳材料（CM），讨论了拉曼光谱在表征无序和异质含碳材料方面的适用性。首先，讨论了测量过程中不同的分析不匹配情况，并提供了技术指导以消除这些情况。其次，回顾了通过传统拟合程序对光谱进行分解所获得的不同参数的准确性和相关性。最后，介绍了一种新的拉曼技术（拉曼面积模式显微光谱），该技术能在大激光束内实现功率的均匀分布，对于研究强异质的含碳材料和/或光敏样品非常有效。
