摘要
A method is described for determining the degree of aromaticity of hard-coal pitches by the proton magnetic resonance (PMR) method in which the contributions to the second moment of the absorption lines of the aromatic and aliphatic components are calculated. A satisfactory correlation of the results obtained by PMR and infrared-spectroscopic methods has been shown.
