The hydrogen bonds in organic compounds present in coal pitch and fractions were investigated by infrared spectroscopy and proton magnetic resonance. The investigation was extended to include pitch that was thermally treated at 360 degrees C to raise the softening point to 85-90 degrees C. The infrared spectra revealed hydrogen present in OH groups, NH groups, COOH groups, unsaturated carbon double bonds, and multiple carbon double bonds. It was also determined that thermal treating increased the hydrogen present in aromatic compounds and decreased hydrogen present in aliphatic forms. (JMT)
