Introduction
NMR spectroscopy is a technique used in order to analyse and determine the structure of chemical molecules, both in organic and inorganic compounds or biomolecules. It is based on the magnetic properties of certain atomic nuclei present in the molecules to be studied. The most sensitive active nuclei in NMR and used in the measurements are 1H, 13C, 31P and 19F, which are also present in most of the molecules both of synthetic and natural origin. When these nuclei are irradiated with radiofrequency pulses inside a stable magnetic field they emit a frequency as a response to the excitation received. The analysis of these resonance frequencies provides information about the nuclei present in the molecule and the relations between them, being it possible to determine their chemical structure; the number of atoms, the type of links that connect them and their spatial arrangement.
Nowadays, the development of any research project in organic, inorganic, organometallic or biological chemistry is inconceivable without the daily and routine support of the NMR.
The equipment of these facilities is co-financed by the European Regional Development Fund (ERDF), with the management of the Ministry of Economy and Competitiveness.
