摘要：

Three Polish coal samples (flame coal, gas coal and orthocoking coal) and their macerals were studied in the solid state by means of C-13 cross polarization/magic angle spinning n.m.r. and FT-i.r. spectroscopies. Several structural parameters derived from these analyses allow the characterization of the three macerals, vitrinite, exinite and fusinite, and their comparison with their parental coal. These structural data were compared with the solvent extraction yields of the same samples with N-methyl 2-pyrrolidone.
