Abstract

The ratio of NMR frequencies of lithium isotopes was determined: with an error of 4,9·10–10. We used a spectrometer mode with simultaneous recording of signals from two cores, which allows us to reduce random and systematic errors by an order of magnitude. The ratio of the resonant frequencies of water protons and 7Li ions was determined: with an error of 3,5·10–9 for solutions with an extremely low concentration of LiOH*H2O salt in water and at a temperature of 25 °C. Based on the data obtained, the magnetic moments of lithium nuclei were calculated. The known data on the magnetic moment of the proton and data on the electronic shielding of these nuclei were used. The comparison of experimental data on µ(6Li) and µ(7Li) with data from theoretical calculations is discussed.
