Sammanfattning

The near-edge fine structure of the F 1s absorption spectra of 3d metal fluorides was studied for the first time with high energy resolution. The spectra of these, the most ionic compounds of the 3d atoms, are analyzed comparing with the F 1s absorption spectrum of the molecular TiF62− anion in solid K2TiF6. The latter spectrum was afore interpreted considering the fluorine spectra of the molecular PF6− anion in a KPF6 crystal and of the gas-phase SF6 molecule. The low-energy empty electron states in the 3d metal fluorides are shown to be formed due to covalent mixing of the metal 3d and fluorine 2p electron states.
