NMRspectroscopy is a spectroscopic method, which is based on the phenomenon of nuclear magnetic resonance. Since this method is very sensitive to local changes in the material, it is widely used to study the structure and properties of various materials, as well as the dynamics of processes occurring in them. 

The main advantages ofNMR: 

      • High resolution – on 10 orders higher, than by optical spectroscopy. 

      • Possibility to consider a number of resonating nuclei. It gives opportunities for the quantitative analysis of the substance. 

      • NMR-spectra depend on the nature of the processes occurring in the substance.  Therefore, these processes can be studied by this method. Moreover, the time scale gets available in a very wide range - from many hours to a small     fraction of a second. 

      • Modern electronic equipment and computers allow to obtain the parameters characterizing the phenomenon in handy for researchers and users NMR form. This is especially important for the practical use of the experimental data. 

      • The spectrometer allows to register the NMR spectra of most elements of the periodic table in a wide temperature range.
