The 13C NMR spectra of samples of heavy crude oil fractions were interpreted. The spectra of all samples were of the same character. In the region of the aliphatic carbon shifts, ten different carbon atom types were discerned; some possible structure types of hydrocarbons were attributed to them and the arrangement of the aromatic rings in a mean molecule of the samples examined was discussed.
