摘要：
We have shown that Raman spectroscopy can be used to determine the free melamine content in melamine-formaldehyde (MF) resins. In contrast to the conventional liquid chromatography method, the Raman spectroscopic method can be directly applied to cured resins without sample preparation. The necessary assignments of bands were supported by theoretical analysis of Raman frequencies. In addition, Raman imaging was used to determine the homogeneity of the free melamine content in cured MF resins.
