Abstract
The electronic structures of the oxides P4O6 and P4O10 are calculated by the self-consistent molecular orbital method including all valence electrons and the 3d orbitals on phosphorus. It is found that the former molecule appears to be virtually non-polar whilst in the latter, the P-O (terminal) bonds are highly polar. The bond order matrix shows that the internal P-P bonding in the P4 unit is not marked.
