Photoelectron spectra of the zinc and cadmium halides
Abstract
The photoelectron spectra of the chlorides, bromides and iodides of zinc and cadmium show that their valence electronic structure is …σ2gσ2uπ4uπ4g. Shifts of the zinc 3d bands in the spectra of the zinc halides are used to estimate the ionic characters of the zinc–halogen bonds. Zinc is shown to be more electronegative than mercury, in agreement with the Aldred–Rochow scale.
