The present report deals with the constitution of the pyridine extracts of some Japanese coals, a study based upon their hydrogen distribution. The pyridine extracts of 6 Japanese coals were separated from the solvent, dried and redissolved into deutero-pyridine, C5D5N. The C5D5N solutions (approx. 10wt.%) of the coal extracts thus prepared were examined by high-resolution NMR spectroscopy at 60Mc. with a JNM-3H-60 NMR spectrometer.
