Core electron binding energy

In an effort to better understand the differences observed upon substitution in carvone possible changes in valence electron density produced by inductive effects, and so on, were investigated [38, 52]. A particularly pertinent way to probe for this in the case of core ionizations is by examining shifts in the core electron-binding energies (CEBEs). These respond directly to increase or decrease in valence electron density at the relevant site. The CEBEs were therefore calculated for the C=0 C 1 orbital, and also the asymmetric carbon atom, using Chong s AEa s method [75-77] with a relativistic correction [78].

One of the first tasks of XPS was the precise determination of core electron binding energies for all elements of the periodic table. These data are now tabulated and available for reference (Table 1). On the other hand, there is a great interest in the measurement of the range of low binding energies (0-20 eV) to get a clearer picture about structure and symmetry of the molecular orbitals.

The quasiparticle approximation has succeeded in the description of valence ionization spectra of many systems. Recently, it has been shown that reliable results also can be obtained for core electron binding energies [26], In this section, we will describe some recent developments that have been realized with the quasiparticle approximation.
