P-NMR spectroscopy is useful to assay purity and to assign structures of phosphorus-containing compounds because these signals are well resolved and often occur at characteristic frequencies. Chemical shifts and coupling constants span a large range but sometimes are not readily predictable. The … See more Phosphorus-31 NMR spectroscopy is an analytical chemistry technique that uses nuclear magnetic resonance (NMR) to study chemical compounds that contain phosphorus. Phosphorus is commonly found in See more With a gyromagnetic ratio 40.5% of that for H, P NMR signals are observed near 202 MHz on an 11.7-Tesla magnet (used for 500 MHz H NMR measurements). Chemical shifts are … See more P-NMR spectroscopy is widely used for studies of phospholipid bilayers and biological membranes in native conditions.

The sharp peaks and broad range of chemical shifts of Phosphorous NMR (31P) make this isotope an ideal candidate for quantitative NMR. The gyromagnetic ratio (½ spin) of the 31P nucleus and high natural abundance allows for more sensitive detection and simple NMR pulse sequences. (Skoog, et al. 1998) (Schiller, et al. 2002) .
