Nuclear magnetic dipole moments from NMR spectra

In the procedure applied to extract the magnetic dipole moments of bare nuclei from NMR spectra of molecules the shielding of nuclei by electrons has been often described in a very crude manner. We determine the moments for 13C, 14N, 15N, 17O, 19F, 31P and 33S using more accurate shielding constants. Our gas phase NMR data are next used to improve the accuracy of the moments of 13C, 17O, 19F and 33S nuclei. We present a new, systematic analysis of the results, based on the relations between the nuclear magnetic dipole moments, the resonance frequencies and the shielding constants.
