The NMR techniques offers non-destructive solid state examination of chemical and physical properties of coal structures. Of the NMR techniques being used for coal studies the most common are based on ^<13>C, using direct polarization due to ^<13>C spin-lattice relaxation approach. But this method has the limitation from the view point of measurement time and information. The present paper discusses the information on chemical functionalities present in three coals and their relative concentrations that provided by multi-nuclear NMR methods.
