Precision Measurements of Magnetic Moments of Nuclei with weak NMR Signals

Abstract

Two NMR spectrometers were combined and a special probe assembly was constructed in order to enable a simultaneous measurement of the signals of 2H and any nucleus, the gyromagnetic ratio of which is <1.4·107T-1sec-1. The Larmor frequencies of 39K, 73Ge, and 109Ag in well defined samples were referred very accurately to the resonance of 2H in D2O. It was possible now, to refer the Lamor frequencies of the nuclei 41K, 57Fe, 87Sr, 107Ag, 183W, 187Os, which were previously referred to the resonance of one of the nuclei mentioned above, to the Larmor frequencies of the deuteron and the proton in D2O or H2O. The magnetic moments of all these nuclei are given.
