Abstract: ¹³C CP/MAS NMR structural parameters of Ostrava-Karviná coals were determined. On this basis their aromatic structures were expressed and discussed. It was found that representative structures of Czech bituminous coals are the clusters with 2—4 aromatic rings (mainly 3—4), 1—2 OH groups (mainly 1), and side cycles (six-membered cyclanes or six-membered oxygen-containing heterocyclanes) with quaternary carbons. The cluster size depends on aromaticity of coal.
