Phosphorus-31 NMR (for nuclear magnetic resonance) is an analytical technique. It is one of the more routine NMR techniques because 31P has an isotopic abundance of 100% and a relatively high magnetogyric ratio. The 31P nucleus also has a spin of ½, making spectra relatively easy to obtain and interpret. Due to the inconsistent nuclear Overhauser effect, integrations are not useful.[1]

Phosphorus is commonly found in organic compounds and coordination complexes (as phosphines), making it useful to measure 31P NMR spectra routinely.

85% phosphoric acid is conventionally used as an external standard.[1]
