Abstract: The necessity of recording the spectrum of nuclear magnetic resonance in a weak field from a condensed medium with express control of its state is substantiated. The conditions are established that allow the registration of nuclear magnetic resonance spectra in a weak field. A new design of a small-sized nuclear magnetic spectrometer for recording the NMR spectrum in a weak magnetic field from a volume of a condensed medium of about 3.0 ml has been developed. The results of experimental studies of various media are presented.

Keywords: nuclear magnetic resonance, signal, weak magnetic field, spectrum, express control, state of the environment.
