Electronic structure of xenon fluorides

The ionization potentials of XeF2, XeF4 and XeF6 are calculated using the selfcoordination discrete-variation Xsub(α)-method. On the basis of comparison of the calculated ionization potentials with the data of photo- and X-ray electron spectra the attribution of the spectra bands, different from the previously suggested one on the basis of non-empiric calculations, is suggested. The calculated energies of the first resolved transitions for XeF2 and XeF6 in the limits 0.2- 0.4 eV coincide with the experimentally measured ones
