【摘要】：为了鉴别文物表面常见的天然有机物,采用显微共聚焦拉曼光谱技术采集了古代常用的蛋白类、多糖类、脂肪酸类、树脂类4类6种有代表性的天然有机物的拉曼光谱。通过对皮胶、桃胶、蜂蜡、棕榈蜡、达玛树脂和琥珀标准样品的拉曼光谱分析,发现蛋白类的特征振动峰位于1657cm-1、1305~1252cm-1、1033cm-1及1003cm-1附近;多糖类的特征振动峰位于1463cm-1、1328cm-1、1258cm-1、1088cm-1、977cm-1等;蜡类的特征振动峰位于1470~1350cm-1区间,1659cm-1、1303cm-1、1636 cm-1及1610cm-1;树脂类的特征振动峰位于1660~1650cm-1区间和1460~1440cm-1区间。在对6种天然有机物光谱特征分析的基础上,得出了使用拉曼光谱法可实现古代文物表面常见天然有机物种类鉴别的结论。
[Abstract]:In order to identify the common natural organic compounds on the surface of cultural relics, the Raman spectra of six representative natural organic compounds, such as proteins, polysaccharides, fatty acids and resins, were collected by microconfocal Raman spectroscopy. The Raman spectra of leather gum, peach gum, beeswax, palm wax, Dama resin and amber standard samples were analyzed. It was found that the characteristic vibration peaks of proteins were in the range of 1657 cm 鈮，
