Аннотация
A new construction of a magnetic system and a circuit for detecting the signal of nuclear magnetic resonance (NMR) in a weak magnetic field are described. The features of NMR-signal detection from a small volume (less than 0.3 mL) of liquid medium in a weak field using the modulation method are determined. Taking these features into account in the new design of the compact NMR spectrometer has made it possible to provide detection of signals from different nuclei of a condensed medium that possess a magnetic moment. The results of the experimental investigations of various condensed media are presented.
