NMR (Nuclear Magnetic Resonance spectroscopy)

Nuclear Magnetic Resonance is currently the most widely used analytical tool in organic chemistry. It makes it possible to obtain qualitative or quantitative information on the sample analyzed, according to the pulse sequence used. The most frequently studied nuclei are 1H, 13C, 31P, 19F and 15N which, for the most part, have a non-zero nuclear spin equal to ½.

The 1H, 19F and 31P NMR is relatively fast and allows easy quantitative analysis. Thanks to the interpretation of the nature of the peaks area obtained on the spectrum (multiplets) and to the empirical knowledge of the chemical shifts of the nuclei present in each functional group, it is possible to identify in part the developed structure of all the organic molecules by application of simple logical reasoning. However, the use of 13C and 15N NMR as well as the use of 2-dimensional sequences are necessary for the complete interpretation of a spectrum and thus for the identification of a molecule.
