The beta-detected nuclear magnetic resonance ( β-NMR) in liquid HO has been observed for the first time using a short-lived β-ray emitter N ( I = 1, T =11 ms). A nuclear spin polarized N beam with an energy of about 20 MeV/nucleon was implanted into an enclosed water sample. About 50 % of implanted N ions maintained nuclear polarization and exhibited a β-NMR spectrum. The chemical shift of N in HO relative to N in Pt was deduced to be −(3.6±0.5) × 10 ppm.
