摘要：

**1**3C solid-state nuclear magnetic resonance spectroscopy was used to characterize 32 low-rank coals from New Zealand and Australia. A combination of high magnetic field (4. 7 T) and resolution enhancement was used to exract spectral details beyond those seen in published spectra of coals of similar rank. Signal heights were used to characterize organic functional distributions. The results of the analysis are used to characterize the coals.
