红外光谱方法,可以在不破坏物貭原有结构的条件下,提供有关物貭分子内部结构的资料。近年来,关于煤的红外光谱,国外已进行过不少研究。我们测定了中国不同变貭阶段镜煤和若干典型煤岩显微成分的红外光谱,其中包括中国独特的乐平树皮煤的树皮貭。试样是用苯和四氯化碳混合比重液离心分离出来的。它们的纯度和基本性貭见表1。光谱是在UR-10型双光束红外光谱仪上测定的。700—2,000cm~(-1)波段使用NaCl
Infrared spectroscopy method can provide information about the internal structure of matter molecules without damaging the original structure of matter object. In recent years, there have been many studies abroad on the infrared spectra of coal. We measured the infrared spectra of the microscopic compositions of mirroring and several typical coal rocks in different stages of transformation in China, including the bark of the bark of the unique Leping bark of China. The sample was separated by centrifugation with a mixture of benzene and carbon tetrachloride. Their purity and basicity are shown in Table 1. The spectra were measured on a UR-10 two-beam infrared spectrometer. 700-2,000cm ~ (-1) band using NaCl
