The determination of the NMR gyromagnetic ratio of deuteron in D2O

Results of measurement of the ratio of the nuclear resonance frequencies of deuterons in D₂O and of protons in H₂O are given. From these measurements the gyromagnetic ratio of deuteron in D₂O is evaluated as _d/2=6·535670(23) (10² HzG^–1). The experimental equipment and method are described and the results are discussed in comparison with the measurements of other authors.Na Slovance 2, Praha 8, Czechoslovakia.
