This behaviour suggests the suppression of the Co–Ni interaction by the stronger NO–Co interaction and correlates the observed chemical shift in XPS to a downshift of the unoccupied dz2 spin level after bonding with NO. On thermal treatment of the NO–CoTPP–Ni system the multiplet feature ...
The chemical states of carbon from the inner side, the center and the outer side of the dome top unit were also studied by XPS. It was found that large peak shift was observed in the inner side of the dome top unit. It indicates that the hydrocarbon absorption layer and re-deposition ...
chemical shift from conventional XPS by the excited-state chemical shift (ESCS), which is connected to the charge in the framework of a potential model. This allows us to invert TR-XPS spectra to the dynamic charge at a specific atom. We demonstrate the power of TR-XPS by using sulphur ...
Non-functionalised CNTs, covalently bonded and non-covalently bonded chemical functionalised MWCNTs, SWCNTs, short CNTs dispersed in different chemical solutions; argon sputtered and thermally annealed have been extensively investigated with a high resolution XPS. Significant chemical shift was observed in ...
Chemical effects in Auger electron spectra of aluminium The bonding and electronic structure of surface atoms is most often studied by XPS, where the energy shift of a photoelectron peak can be ascribed to a cha... B Timmermans,N Vaeck,A Hubin,... - 《Surface & Interface Analysis》 被引...
The density-proportional chemical shift observed by Carr and his associates in xenon gas can be used as a means of calibrating the spin-rotational coupling existing in a diatomic xenon system during collisions of xenon atoms. The basis of this calculation is Ramsey's theory of chemical shifts. ...

It can distinguish TM in the different chemical states in solid from the chemical shift of the inner core-photoelectron. However, there are some reports that the irradiation of X-rays during measurement induces changes in the valence states of TM ions [3], [4], [5], [6], [7]. ...
