We have employed synchrotron radiation resonant photoemission technique to investigate the electronic structures of one of the prototype organic electroluminescent polymer Poly(p-PhenyleneVinylene) (PPV). When the photon energy was near the binding energy of C 1s core level, at least three strong resonacnes at the approximate binding energies of 5, 6.5, and 9 eV could be observed We discuss the origin of the observed resonances and identify the symmetries of related valence energy levels. The results of resonance photoemission on Ca-induced gap states formed in near-surface region of PPV thin film were also discussed.
