N2 - The HeI photoelectron spectra of the complexes n4-l- vinylnaphthalene-Fe(CO)3 and n4-2-vinyl-naphthalene-Fe(CO) 3 and the free organic ligands 1-vinylnaphthalene and 2-vinylnaphthalene are measured. The spectra are interpreted on the basis of quantum-chemical calculations by the density functional method in the SVWN/6-31G(d) local density approximation and with the B3LYP/6-31G(d) hybrid exchange-correlation functional. The Kohn-Sham orbital energies with calibration corrections are shown to reproduce well the vertical ionization potentials of both the irontricarbonyl π complexes under study and their ligands. The relative ionization cross sections σi of the valence orbitals of the complexes are calculated in terms of the Gelius model. These quantities prove to agree perfectly with the relative ionization cross sections σiexp determined experimentally from direct estimation of the band areas of the photoelectron spectra.
