“…In reviewing photoemission, we describe the main features of the technique without giving much of the theoretical background, which can be found instead in the respective references. 93,113,114 The electron range is discussed in the context of the probing depth of the technique. Although the electron range in matter has been studied in great detail over the past several years, 115 there is still considerable controversy regarding the reliability of the experimental data, which depend sensitively on experimental conditions.…”

“…PE spectra of atoms and molecules usually exhibit rather narrow lines, which in condensed matter, are broadened as a result of electronphonon coupling, chemical bonding, and other interactions. 113,114 Also, electronic valence states of all elements are concentrated in a comparatively small energy range, whereas inner shell energies are usually well separated from neighboring emission lines. In the valence-band region of a solid, symmetry selection rules, when paired with the suitable choice of experimental parameters (such as light polarization, detection angle, etc.…”

Abstract:A series of ferrocenyl-functionalized β-diketonato manganese(III) complexes, [Mn(FcCOCHCOR) 3 ] with R = CF 3 , CH 3 , Ph (phenyl) and Fc (ferrocenyl) was subjected to a systematic XPS study of the Mn 2p 3/2 and Fe 2p 3/2 core-level photoelectron lines and their satellite structures. A charge-transfer process from the β-diketonato ligand to the Mn(III) metal center is responsible for the prominent shake-up satellite peaks of the Mn 2p photoelectron lines and the shake-down satellite peaks of the Fe 2p photoelectron lines. Multiplet splitting simulations of the photoelectron lines of the Mn(III) center of [Mn(FcCOCHCOR) 3 ] resemble the calculated Mn 2p 3/2 envelope of Mn 3+ ions well, indicating the Mn(III) centers are in the high spin state. XPS spectra of complexes with unsymmetrical β-diketonato ligands (i.e., R not Fc) were described with two sets of multiplet splitting peaks representing fac and the more stable mer isomers respectively. Stronger electron-donating ligands stabilize fac more than mer isomers. The sum of group electronegativities, Σχ R , of the β-diketonato pendant side groups influences the binding energies of the multiplet splitting and charge transfer peaks in both Mn and Fe 2p 3/2 photoelectron lines, the ratio of satellite to main peak intensities, and the degree of covalence of the Mn-O bond.

“…It was originally developed to obtain reliable intensities of valence band spectroscopy for investigating bulk as well as surface characteristics [34], so bringing the accuracy on an equal footing with LEED calculations where refined computer codes existed. [57,58,90] Thus, the scattering in the bulk and at the surface is condensed into a coherent final state which must be introduced into the matrix element of photoexcitation, the so-called time-reversed LEED state.…”
