Abstract
Due to the proportionality between the area of the NMR signal and the number of nuclei, internal standard31P NMR spectroscopy is in principle a rapid and simple method for determination of the purity of phosphorus compounds.nuclei, internal standard31P NMR spectroscopy is in principle a rapid and simple method for determination of the purity of phosphorus compounds.nuclei, internal standard31P NMR spectroscopy is in principle a rapid and simple method for determination of the purity of phosphorus compounds.nuclei, internal standard31P NMR spectroscopy is in principle a rapid and simple method for determination of the purity of phosphorus compounds.
