Peculiarities of Registration of the Nuclear Magnetic Resonance Spectrum of a Condensed Medium During Express Control of Its State.

The necessity of recording the spectrum of nuclear magnetic resonance (NMR) in a weak field from a condensed medium during express control of its state is substantiated. The conditions have been established that make it possible to record the NMR 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. [ABSTRACT FROM AUTHOR]
