Sapropelitic coals of various coalification stages were examined using FT-i.r. spectroscopy and X-ray diffraction (XRD). The FT-i.r. spectra showed that the main constituent of low-rank sapropelitic coals is aliphatic chains. The evolution of carbonyl groups is more likely to be related to rank chan

Several Canadian coals were analysed by FT-i.r. The technique is applicable to both the organic and inorganic part of the coal. The method by which the spectra can be subtracted one from the other, allows the distinguishing of one coal from another by characteristic functional groups. The high resol

Nine liquid products from processing of high-and low-rank coals, oil shale and crude oil were analysed by quantitative FT-i.r. spectroscopy to understand the effect of sample structure on the absorptivities for aliphatic and aromatic CH bonds. Variation in the structure of samples was additionally e
