Study of the electronic structure of polynuclear cobalt trimethylacetate complexes by Co3s and Co3p X-ray photoelectron spectroscopy

Morphological and structural characterisation of sol–gel electrospun Co3O4nanofibres and their electro-catalytic behaviour

“…6a. The major characteristic peaks are assigned to cobalt (Co 3p, Co 3s, LMM, Co 2p and Co 2s), oxygen (O 1s, KVV) and carbon (C 1s) 28,29 and their respective high resolution spectra are shown in Fig. 6b-d, respectively.…”

X-ray photoelectron spectroscopy study of electron and spatial structure of mono- and binuclear Ni(II) carboxylate complexes with nitrogen-containing ligands

“…Experimental Ni3p-spectra of the compounds are shown in Figure 3, where they are compared with calculated spectra for atoms in configurations 3d 10 (panel a) and 3d 8 (panel b). In the calculation of the 3p-spectra the integrals of electrostatic interactions were scaled with the factor 0.77.…”

“…Our results demonstrate the potential of XPS as a tool for studying electron and spatial structure of metalloorganic complexes. Experimental Ni3s-spectra of the complexes (I -V) and Ni3s-spectra of the Ni atoms in configurations 3d 10 and 3d 8 , calculated in this study (a, b). The calculation of [18] is in panel (c).…”

“…After 3s-ionization on the background of completely filled levels, there appears only a single state 3s 1 , which gives one line in the 3s-photoelectron spectrum. In the isolated-ion approximation, the situation in the complex (I) can be simulated with the atomic configuration 3d 10 . The result of such a calculation is shown in Figure 2a.…”

“…The results of the previous calculations performed in refs [4,6,10] showed that this approximation, albeit rather crude, allows, however, to describe the basic details of the structure of the spectra and their change upon going from one compound to another.…”
