Abstract
Carbon aromaticities for a selection of 19 bituminous coals and vitrin ite concentrates have been obtained by solid-state C-13 n.m.r. using t he inherently quantitative single pulse excitation technique. Within e xperimental error, the aromaticity values in the range 0.75-0.90 corre late extremely well with the H/C ratios (R(2) = 0.93); the 11 samples investigated with H/C ratios between 0.74 and 0.77 all have aromaticit ies in the range 0.75-0.81. Furthermore, the correlation holds for the coals investigated with high inertinite contents.
