Abstract

Abstract: Gas‐phase 21 Ne nuclear magnetic resonance spectra were measured at the natural abundance of 21 Ne isotope for samples consisting of pressurized neon up to 60 bar at room temperature and applying the magnetic field of the strength B 0 = 11.7574 T. It showed that the nuclear magnetic resonance frequency is linearly dependent on the density of gaseous neon. The resonance frequency was extrapolated to the zero‐density point, and it permitted the determination of the 21 Ne nuclear magnetic moment, μ ( 21 Ne) = 0.6617774(10) μ N . The present value of μ ( 21 Ne) is not influenced by the bulk magnetic susceptibility of neon and interactions between neon atoms; therefore, it is more precise and reliable than the previous result obtained for μ ( 21 Ne). Abstract : On the basis of the measured 21 Ne and 1 H resonance frequencies and recent literature values of the proton magnetic moment and nuclear magnetic shielding of a neon atom, we determined the nuclear magnetic moment of neon‐21, µ ( 21 Ne) = −0.6617774(10) µ N. This value is in agreement with previous results obtained using the atomic beam magnetic resonance method.
