For simplicity we will only deal with proton decoupled 13C NMR spectra.
These ring-numbers were directly related to the number average molecular mass (Mn) assigned to the particular fraction in the average structural parameter (ASP) calculations.

HMDB ID: HMDB0001659: Compound name: Acetone: Spectrum type: 13C NMR Spectrum: Spectrum View. Preparation of the Mesophase Pitch by Hydrocracking Tail Oil from a Naphthenic Vacuum Residue. To improve the spectra allowing easy counting of the number of carbons, the protons are often irradiated at a frequency that excites prottons and gives singlets. This made it possible to calculate the average structural parameters for the higher molecular weight (MW) fractions of the coal tar pitch. Anthony, Y. Sarbassov. Catalysts.

The same solvents are used for 13 C NMR spectra, so the same rules about splitting patterns apply here also. 13C 1/2 1,108 6,7283 16O - 99,96 - 17O 5/2 0,037 - 3,6279 Tabelle 1: NMR-relevante Daten einiger Atomkerne Die Tabelle zeigt, dass beide Bedingungen für das natürliche Wasserstoffisotop 1H in idealer Weise erfüllt sind, so dass es im Nachhinein kein Wunder ist, dass dieser Kern als erster der NMR-Spektroskopie zugänglich war.

13C is a naturally occurring isotope of carbon that has a nuclear spin.

The aromaticity and the average number of aromatic rings per polynuclear aromatic structure were both found to decrease with increasing solubility.
