13C-Enriched poly(p-phenylene) PPP prepared by dehalogenation polycondensation of 13C-enriched p-diiodobenzene with Ni(0) complex gives basic data for assignment of the IR vibration modes of PPP, reveals the magnitude of magnetic dipole interaction in the NMR spectrum, and indicates considerably small coupling of spin with 13C-nuclei in the ESR spectrum presumably due to rapid movement of electrons.
