The electronic structures of polynuclear aromatic compounds are studied as the electrically conductive fragment models in pyrolyzed polymers. It is found that the manner of the distribution of the frontier electrons, which is important in determining the path of the conduction carriers, can be broadly classified into two groups depending on the shape of each fragment.
