shake up satellitesShake-up satellites found in photoemission spectroscopy from core levels of adsorbed atoms are considered using a simple diatomic molecule model. Time scales and the competition between surface plamons and shake-up for the satellite strength are considered....
Solid state XPS spectra of bis(4-dimethylaminophenyl)squaraine and a number of derivatives are presented. The complex multipeak N1s and O1s satellite spectra are analyzed in terms of intra and inter-molecular contributions and related to corresponding electronic transitions of the neutral species. It...
INDO/CI calculations were used to analyze the C1 s and O1 s shake-up spectra of nickel tetracarbonyl, Ni(CO) 4 . The satellite structure in both cases is dominated by excitations from metal–ligand bonding (2Π b ) to metal–ligand antibonding (2Π a ) orbitals and by excitations ...

The spectroscopic analysis suggests that the presence of oxide layer is not the prime cause but the surface chemical property is equally responsible for the shake up satellite peak in X-ray photoelectron spectrum (XPS). \\\{XPS\\\} spectra of a-HCNx films show a strong shake up peak where...

We report here a study of the Ag L 23 M 45 M 45 spectra as a function of photon energy and demonstrate the evolution of the line shapes of the satellite spectra. The transition from the adiabatic to sudden approximation regimes appears to occur at around 80 eV above threshold, which is ...
On the basis of a multiple scattering calculation in ThO 2, these satellites are assigned to ligand (e.g. O 2p) to Th 5f shake-up transitions. As with La 3d satellites, the satellite intensities correlate well with the nephelauxetic order of ligands....
