摘要

通过红外（IR）和拉曼光谱研究了无烟煤的结构特征。研究了来自 Bungursky、Krasnogorsky 和 Listvyansky 矿山的三种无烟煤样本。它们的无烟煤反射系数从 2.58% 到 5.26% 不等。对红外光谱数据的分析表明，玻璃光泽反射系数最大的无烟煤（Listvyansky 样品）具有最大的芳香参数（fa、AR1 和 AR2）。其有机质含有较短和较多支链的脂肪族侧链，这一点从较低的 CH2/CH3 比率中可以得到证实。拉曼分析证实，有序的石墨状结构碎片在利斯特维扬斯基无烟煤中占主导地位

Spectral Analysis of Anthracite

The structural features of anthracite are investigated by infrared (IR) and Raman spectroscopy. Three anthracite samples from the Bungursky, Krasnogorsky, and Listvyansky mines are studied. Their vitrinite reflection coefficient varies from 2.58 to 5.26%. Analysis of IR spectroscopic data shows that the anthracite with the largest vitrinite reflection coefficient (the Listvyansky sample) has the greatest aromatic parameters (f_a, AR1, and AR2). Its organic mass contains shorter and more branched aliphatic side chains, as confirmed by the low CH₂/CH₃ ratio. Raman analysis confirms that ordered graphite-like structural fragments predominate in the Listvyansky anthracite
