Abstract
High-resolution nuclear magnetic resonance techniques were used to perform a precise measurement of the ratio of the Larmor frequencies of tritons and protons in a sample of 20% tritiated water. The measured ratio ωTωH is 1.066 639 75(2). From this frequency ratio and an estimate of the magnetic shielding correction, a value of 1.066 639 86(11) is obtained for the moment of the triton in units of the proton moment. From this value and the hfs measurements of Kusch, and of Prodell and Kusch, one obtains a hfs anomaly of (-5.62±0.13)106 for tritium. This observed anomaly is compared with the theoretical predictions of Adams. The longitudinal relaxation time T1 of the protons and tritons in the sample was measured and found to be 1.02±0.10 sec. and 0.83±0.10 sec., respectively.
