Andreas Orthaber, Ferdinand Belaj and Rudolf Pietschnig, Comptes Rendus Chimie 13 (2010), 923–928. Section 3.2 analyses the strongly polar P–O sigma bond and oxygen lone-pair negative hyperconjugation; this is not a claim that every orbital-localization scheme assigns the same bond order.

Ferdinand Belaj coauthored structural research on a hydrogen-chloride adduct of trimethylphosphine oxide. The work combines molecular geometry with calculations of the phosphorus-oxygen bonding framework.
Comparing these approaches helps distinguish a measured atomic arrangement from a model-dependent partition of electron density into localized chemical bonds.[ref]
