Abstract

Solvent effects on the P → O and [P — O]G absorptions in organophosphorus compounds of the type (GO) ₃P → O, (GO) ₂G'P → O, [(GO) G'PO (OH)]₂, [(GO) ₂PO(OH)]₂, and G₃P → O are described, where G is an alkyl or aryl group. The unassociated phosphoryl dipoles are affected by solvents in a manner similar to the carbonyl dipole. The consequences of the solvent effects on the physical properties of these compounds are discussed.
