摘要
作者研究了煤化度相近的两组煤镜质组氯仿抽出物及其石油醚抽出物的萤光参数。研究表明,它们均发荧光,且荧光光谱没有大的区别,仅红绿商 Q 和最大荧光强度波长λ_(max)差别较大。~1H-NMR 分析表明,两组煤的氢分布差异较大,第一组煤镜质组氯仿抽出物的脂肪氢含量较丰富。
The fluorescence parameters of the chloroform extract and petroleum ether extract of two groups of vitrinoid of somewhat similar coalification are studied.Both groups give fluores- cence;and their fluorimetric spectra are not greatly different from each other except for some dis- tinct difference in Q(red/green)and λ_(max)(wavelength of maximum fluorescent intensity).~1H- NMR analysis shows:there is a considerable difference in hydrogen distribution of the two groups,with the CHCl_3 extract from the lst vitrinoid group more abundant in paraffinic hydro-
