WebP-31 NMR shift calculator Using this calculator you can predict the chemical shift (ppm) value for around 14000 primary [PH 2 R], secondary [PHR 2] and tertiary [PR 3] phosphines (phosphanes). 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 organic compounds and coordination complexes (as phosphines), making it useful to measure P NMR … 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 referenced to 85% phosphoric acid, … See more 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 … See more P-NMR spectroscopy is widely used for studies of phospholipid bilayers and biological membranes in native conditions. The analysis of P-NMR spectra of lipids could provide a wide range of information about lipid bilayer packing, phase transitions … See more

In this study, an enzyme assay is presented that determines the average chain length of polyphosphate in the range of two to several hundred P-subunits. In the enzyme assay, the average polyP chain length …
