Abstract
Nuclear magnetic resonance spectra of the hydrogen isotopic analogs TH and TD on the triton resonance and HT, HD, and H2 on the proton resonance in the gas phase have been studied. The triton and proton spectra from a single sample have been recorded simultaneously by using the inductivity of a common receiver LC circuit. The energies of the interaction between the magnetic moments of the nuclei of the hydrogen isotopic analogs have been determined: J tp = 299.3(1) Hz, J td = 45.5(1) Hz, and J pd = 43.3(1) Hz. The ratio of the resonance frequencies of the HT molecule nuclei: F t (TH)/F p (HT) = 1.066693898(2), which is equal to the ratio of the magnetic moments of the nuclei in the bound state, has been obtained. If the value Δσ(TH) = 2.04 × 10−8 calculated previously is used for the difference in the screening of nuclei in the HT molecule, then the ratio of the magnetic moment of the triton to the magnetic moment of the proton is μ t /μ p = 1.066693920(2), where the statistical standard deviation of the data is given in the parentheses in the units of the last digit.
