In this work, the influence of the properties of the medium on the possibility of recording an NMR signal in a weak magnetic field was determined. A new methodology for recording an NMR signal using the contributions of absorption and dispersion signals is proposed. The features of the use of spectral analysis in the study of the NMR signal from liquid media are determined. A comparison of the results of theoretical calculations and experimental studies is carried out. |
