摘要：
The isotropic Compton profiles of vanadium oxides VO, V2O3, VO2, V6O13, and V2O5 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.
