Abstract: In this article three methods(inverse gated dec,J-modulated spin-echo and 2D-J-resolved) for measuring the protonated and non-protonated carbons were dis-cussed and compared. The average molecular parameters of three kinds of polycyclic aromatic hydrocarbons derived from petroleum and coal were independently calculated by three methods,and the structure of three complex mixtures were primarily analysedand discussed.

Key words: 13C NMR, Polycyclic hydrocarbona, J-modulated spin-echo, 2D-J-resolved
