| Abstract: | A set of coal extracts have been characterized by FT-i.r. and proton n.m.r. spectroscopy. The n.m.r. measurements of aliphatic and aromatic hydrogen allow a direct calibration of the absorption coefficients of appropriate i.r. bands. This allows methods for calculating these coefficients based on relating i.r.-band intensities to elemental hydrogen to be tested directly. Reasonable agreement was obtained. |
