PACS numbers: 61.48.-c, 76.60.-k, 81.05.U-, 81.07.-b, 81.16.-c, 81.70.Pg, 88.20.G-
Evolution of carbon-atomsĺ distribution among functional groups in coal at different stages of metamorphism are investigated using 13Đ NMR MAS and Đđ MAS spectroscopy. The relationship between composition, structure and outburst hazard is determined.
