✦ Synopsis

A series of 0,O'-dialkyldithiophosphoric acids have been studied hy 31P NMR, and a four-bond 31P-1H scalar coupling has been detected. This coupling is unusual because it is observed between phosphorus and only one of two available protons located on the same carbon, even when the alkyl fragment is simply an alkane that should not show any conformational preference. Variation of the structural features of the alkyl group showed that this coupling involved a "W" pathway.

## Abstract A full line‐shape analysis of the VT ^31^P NMR spectra was carried out for the monomer–dimer equilibrium of neutral ZDDP. The energy surface and the energetics of the monomer‐dimer equilibrium (Δ__H__° , Δ__G__° , __E__~a~, Δ__H__^≠^, and Δ__G__^≠^) are reported for three variants where
