The aromaticities of samples from nine Australian coal seams, including pairs of hand-picked vitrains and durains, have been determined by 13C cross-polarization n.m.r. spectroscopy with magic angle sample spinning. The results clearly show that the aromaticity (f,) of the coals increases with incre
