Angle-resolved ultraviolet photoelectron spectra were measured for oriented films of perfluorotetracosane, n-CF3(CF2)22CF3, as a model compound of poly(tetrafluoroethylene) using synchrotron radiation. The main spectral features showed continuous changes in both peak positions and intensities with photon energy, incident angle, and photoelectron take-off angle. The intramolecular energy-band dispersion of poly(tetrafluoroethylene) was mapped from the photo-energy dependence of the normal emission spectra.
