High-resolution techniques for nuclear magnetic resonance (NMR) in solids have been used to obtain spectra of /sup 13/C and /sup 1/H in an Iowa and a Virginia vitrain. The carbon spectrum separated into two well defined peaks from which an aromatic and aliphatic portion was estimated. A superposition of Lorentzian lines was used to represent the aliphatic and aromatic proton signals, which were not well separated under high-resolution techniques. The fractions of aromatic carbon and hydrogen thus obtained were used to estimate an average polynuclear aromatic ring size in the coals studied.
