Identification of localised and delocalised adsorbate orbitals on W(100) by photoelectron spectroscopy

The comparison of the photoelectron spectra of chemisorbed layers taken with glancing photon incidence and those with normal photon incidence permits a qualitative determination of the degree of delocalisation of the various orbitals at the surface.

Description
Summary:The comparison of the photoelectron spectra of chemisorbed layers taken with glancing photon incidence and those with normal photon incidence permits a qualitative determination of the degree of delocalisation of the various orbitals at the surface. For glancing photon incidence, both localised and delocalised orbitals can be photoionised. However, for normally incident photons, those orbitals localised around particular atomic sites have a much higher photoionisation cross section than those orbitals extensively delocalised in the plane of the surface. Examples of this behaviour in the spectra of hydrogen and carbon monoxide on W(100) are presented.
