Abstract
A precision measurement of the ratio of the magnetic moment of the proton to that of the deuteron has been carried out by the magnetic resonance method. The measurements were made using mixtures of H2O and D2O and also mixtures of H2 and D2 gas. The result for the H2O:D2O mixture is whileforthe H2:D2 mixture     {μHμD=3.2571999±0.0000012,}{μHμD=3.2571990±0.0000010.}
