The β-ray detected nuclear magnetic resonance (β-NMR) of a short lived-nucleus 17N (I = 1/2, T1/2 = 4.173 s) in liquid H2O and CH3NO2 has been performed. A π-pulse method was applied to obtain sharp NMR lines, from which the ratio of the Larmor frequencies of 17N in CH3NO2 and 1H was determined to be ν[17N in CH3NO2]/ν[1H2O] = 0.1265751 ± 0.0000019. Two resonance lines were observed for 17N in H2O with the relative frequency shifts of –(2.33 ± 0.37) × 10−4 and (2.91 ± 0.27) × 10−4 referenced to 17N in CH3NO2.
