Abstract—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 (fa, 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
