Data are presented for a series of whole coal and coal macerals using conventional cross-polarization magic angle sample spinning nuclear magnetic resonance spectroscopy (CP/MAS C-13 NMR), dipolar dephasing, and 2-D dipolar dephasing techniques. These data provide new structural information and demonstrate that multiple pulse and 2-D spectroscopic techniques can be utilized on complex carbonaceous materials. Data are also presented for maceral samples separated by the density gradient centrifugation method. 6 figures, 3 tables. (ATT)
