Abstract
High resolution synchrotron photoelectron spectra (PES) of propene (C3H6) have been obtained at several photon energies (40–70 eV). The full valence shell binding energy spectrum reveals a well resolved correlation (satellite) peak at 20.3 eV and the photon energy dependence study of its photoionization cross section indicates that this new correlation peak is a “dynamic” correlation peak. MRSDCI calculations of the theoretical spectrum show semi-quantitative agreement between experiment and theory in terms of binding energies and intensities. A comparison of the full valence shell photoelectron spectra of ethylene, propene, 1-butene and 1,2-propadiene (allene) is also presented to illustrate trends in the correlation peaks of model alkenes.
