N2 - The low signal-to-noise ratio is a characteristic feature of NMR experiments in the Earth’s magnetic field. The main problem of such studies is the ineffectiveness of signal accumulation due to fluctuations of the Earth’s magnetic field because of magnetic interferences from laboratory equipment and other magnetic field sources. Taking into account the fact that generally in the Earth’s magnetic field, proton-containing liquids have spectra with a strong central line, a relatively simple method has been developed to neutralize the influence of Larmor frequency fluctuations. The NMR signal processing algorithm is described. The home-built NMR-equipment allows us to clearly register the splitting in proton spectra, for example, due to the J-interaction with such nuclei as 29Si or 13C at their natural abundance (4.7 and 1.1%, respectively).
