Gas‐phase 21Ne nuclear magnetic resonance spectra were measured at the natural abundance of 21Ne isotope for samples consisting of pressurized neon up to 60 bar at room temperature and applying the magnetic field of the strength B0 = 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 21Ne nuclear magnetic moment, μ(21Ne) = 0.6617774(10) μN. The present value of μ(21Ne) 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(21Ne).

气相 21 Ne 核磁共振研究和氖 21 的核磁偶极矩

气相 21Ne 核磁共振谱是在 21Ne 同位素的自然丰度下测量的，样品由室温下高达 60 bar 的加压氖组成，并施加强度为 B0 = 11.7574 T 的磁场。它表明核磁共振频率与气态氖的密度呈线性关系。共振频率外推到零密度点，它允许确定 21Ne 核磁矩，μ(21Ne) = 0.6617774(10) μN。μ(21Ne)的现值不受氖体磁化率和氖原子间相互作用的影响；因此，它比之前为 μ(21Ne) 获得的结果更精确和可靠。
