A sample of kerogen from Aleksinac oil shale was examined by high-resolution solid-state Iac n.m.r. spectroscopy. The presence and relative proportions of kerogen structural units were estimated using a combination of NQS and Tlpc methods with a peak-synthesis technique applied to the 13C CP-MAS spe
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
