NMR Spectroscopic Properties of Phosphines

The P nucleus has a spin of 1/2 and is 100% abundant. Its receptivity, a measure of the sensitivity toward NMR analysis, is 0.0665, in comparison with 1 for protons and 0.000175 for Thus, P NMR spectroscopy is an important method for the characterization of organometallic complexes. This subject has been extensively reviewed. -
