The structural parameters of the average pitch molecules have been compared based on the 1H and 13C NMR spectra. It was shown that, in terms of chemical composition and empirical properties including carcinogen content, the extractive pitches resemble blended pitch sample, the structural parameters being close to commercial coaltar pitch sample. The average pitch molecule of extractive pitches was composed of predominantly aromatic nuclei with rather pericondensed structure
