Several pitches, used to make high-grade cokes, are characterized by 13C and 'H n.m.r. spectroscopy. Average molecular parameters of solvent fractions of the pitches indicate distinct differences in molecular structure. Principal differences between A-240 petroleum and medium coal-tar pitches are co
