我们描述了测量，精确到百万分之一，旋磁比的质子在水中，π 'p，由强场方法。磁体的磁感应强度是通过称量施加在矩形载流线圈上的力来测量的，该矩形载流线圈的下端在极隙中。同时，利用常规核磁共振技术获得了该场中水样中质子的进动频率。因此，ω 'p是进动频率与磁通量密度的比率。
We describe a measurement, accurate to a part in a million, of the gyromagnetic ratio of the proton in water, γ'p, by the strong field method. The magnetic induction of a magnet is measured by weighing the force exerted on a rectangular current-carrying coil which has its lower end in the pole-gap. Simultaneously the precession frequency of protons in a water sample in this field is obtained by a conventional nuclear magnetic resonance technique. γ'p is then the ratio of the precession frequency to the magnetic flux density.
