摘要：

The proton nuclear magnetic resonance spectra of α-phenylethylphosphine and its P-monodeuterated derivative have been analyzed. The results show that inversion of the pyramidal structure of the phosphorus atom is slow on the nmr time scale, and a lower limit of 26 kcal/mol is estimated for ΔF≠. The analysis revealed that the diastereomeric P hydrogens of the deuterated compound have nonequivalent nmr parameters of which the different 1JPH values are particularly interesting.
