红外显微光谱分析和拉曼光谱分析已被应用于多层涂料碎片的检测，用于刑事鉴定。研究表明，在所使用的条件下，可见范围(633 Nm)的拉曼光谱提供了有关颜料的数据，但提供了很少或根本没有关于聚合物的信息。红外线被发现可以很好地表征聚合物，但无法提供一些颜料的有用数据。结果表明，在许多情况下，至少主要色素应该是可行的拉曼光谱鉴定。用MU-XRF技术证实了色素的存在。(C)2006爱思唯尔B.V.保留所有权利。
Infrared microspectrometry and Raman spectroscopy have been applied for examination of multilayer fragments of paints, for criminalisctic purposes. The study showed that under the conditions used, Raman spectra in the visible range (633 nm) provided data on the pigments but gave little or no information about polymers. Infrared was found to be good for characterising the polymer but failed to provide useful data on some pigments. The results suggest that in many cases the identification of at least the main pigments should be feasible by Raman. The presence of identified pigments was confirmed by means of mu-XRF technique.
