Linear dual-parameter equations relating the 31P NMR chemical shifts in a series of phosphoryl compounds XYZP = O (X, Y, Z = various organic substituents or halogens) with the sums of inductive (σI) and resonance (σRO) constants of the substituents have been obtained. The direction of the influence of the inductive and resonance components of the electron demand of substituents, and their relative contributions to the δ31P values, have been evaluated. The nature of the resonance contribution is discussed on the basis of the dependence between δ31P values and the charge characteristics of the phosphorus atom (x-ray P Kα shifts).
