Abstract:

High resoln. H NMR measurements combining the MREV-8 multiple pulse sequence and magic angle spinning were carried out to est. aliph. and arom. portions of protons in brown coal. Contrary to the situation in bituminous coals, there is a signal from remaining water even in carefully dried samples of brown coals. Two different line deconvolution strategies are applied to recalc. the real aromaticity value.
