摘要：
This paper studies ten Chinese coals at different ranks by means of cross polarization and magic angle spinning, combined rotation and multiple-pulse spectroscopy, and dynamic nuclear polarization. NMR is first reported. It is found that, compared with those obtained previously coat somples from other parts of the world, some Chinese coals at lower ranks display unusual characteristics, which imply peculiar chemical structures in the coals.
