Free delivery for many products! WebDecoupling 31P from 1H on the UI400 or U500 is easily accomplished with the standard QUAD probe. This handout outlines a procedure to acquire 1H{31P} spectra, where the phosphorus decoupling can be selective or non-selective. If you want to run this experiment on the U400 or VXR500 a cabling change is required.

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 characteristic frequencies. Chemical shifts and coupling constants span a … 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 WebMay 22, 2013 · Yes, the most stable isotopes are 31P, 32P, and 33P. 31P is stable with 16 neutrons. 32P has a half-life of 14.28 days with 17 neutrons. 33P has a half-life of 25.3 days with 18 neutrons.
