## Abstract The signs and magnitudes of every fluorineโfluorine coupling constant in perfluoroquinoline (**1**), 2,4โdichloropentafluoroquinoline (**2**) and 2โbromohexafluoroquinoline (**3**) have been determined by ^19^F n.m.r. These provide an unambiguous assignment of the spectrum of the first
13C 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-inertinit
