Özet

C-13 solid-state n.m.r. spectra of samples of 14 coals and their pyridine residues representative of the three depositions in the Shanxi province of the People's Republic of China are described in detail. The results confirm those of previous infrared spectroscopy in showing these vitrinite-inertinite coals to have similar chemical structures and aromaticities to coals of the same rank from Euramerica and Gondwana.
