摘要
系统分析了广西未变质煤、区域变质煤、岩浆变质煤和热液变质煤的拉曼光谱特征．在拉曼光谱图上主要出现芳烃（ＣＨ面外变形振动），Ｃｎ，Ｃ－Ｏ－Ｃ和－Ｓ－Ｈ等散射峰．一般随变质程度升高，煤的拉曼散射谱基线由上凸曲线变为近水平直线，散射峰的数目逐渐增加．
The Raman spectroscopic patterns of unmetamorphosed, regionally metamorphosed coals in Guangxi have been systematically analysed. The scattered Peaks of arene (out-of-plane deforming vibration of CH grouP), Cm.C-O-C and -S-H etc. appear in the Raman spectrogram. In general, the background scattered line of coal will be changed from a convex-up curve to a near-horizontal straight line, and the numbers of scattered Peaks will increase gradually with an increase in coal rank.
