On the possibility of express recording of nuclear magnetic resonance spectra of liquid media in weak fields

The necessity of recording nuclear magnetic resonance (NMR) spectra in weak magnetic fields during the express control of liquid media has been substantiated, and the conditions in which such recording is possible have been determined. A new scheme of a compact NMR spectrometer intended for such measurements has been proposed. The results of experimental investigation of some substances based on the developed technologies are reported.
