Photoelectron valence-band spectra ofPbF2,SbF3, andBiF3

Abstract
The results of a photoelectron study of the molecular solids PbF2, BiF3, and SbF3, taken with a helium discharge source, are compared with molecular-orbital calculations which use a geometry based on crystal data and which include a crystal potential. The features of the valence-band spectra for these solids are successfully interpreted in this way.
