FT-i.r. studies of acid-demineralized and cation-loaded lignites demonstrate that exchange methods presently being used to determine carboxylic acid groups in coal produce systematic errors. An i.r. method based on intensity measurements of the 1710 cm-' carboxylic acid C=O stretching mode is report

Three H-Coal liquids, ASO, ASB, and VSO, have been characterized by quantitative FT-n.m.r. spectroscopy. FT-parameters were chosen to allow determination of aromatic:aliphatic carbon ratios to within 1% and 2% error of the theoretical and the absolute number of aromatic and aliphatic carbons in a si
High-resolution gated decoupling 13C spectra of soluble materials such as coal extracts have been analysed to evaluate the carbon aromaticity if,). A correlation was found between fa and the reciprocal of the square of the shorter component in spin-spin relaxation time (Tz), which was obtained by pu
Selected, multiplet 13C n.m.r. spectra are obtained for three test samples deriving from petroleum and coal sources, by combining gated spin echo (GASPE) and conventional spin echo 3C n.m.r. procedures. Each selected multiplet spectrum contains resonances due to only one of the following groups: aro
