Abstract

The isotropic Compton profiles of vanadium oxides VO, V₂O ₃, VO₂, V₆O₁₃ and V ₂O₅ were measured by using 59.54 keV gamma -rays. The Compton profiles calculated by using the molecular-cluster model were found to be improper in describing the experimental results of VO and VO₂. The molecular-cluster model seems to underestimate the metal-ligand covalency. The localization and delocalization of valence electrons when forming oxides will be discussed on the basis of the atomic superposition model.
