Principle

The physical and chemical properties of the environment surrounding the observed nuclei change its magnetic properties and thus from its magnetic behavior conclusion on the molecule’s structure can be made.

This measurement relies on the phenomenon of nuclear magnetic resonance with electromagnetic radiation and can therefore provide detailed information on the structure, dynamics, reaction state, and chemical environment of molecules.

The total magnetic field acting on the atom of interest in a molecule changes its resonance frequency and therefore allows for information on the electronic structure of the molecule.

Frequently observed nuclei are 1H, 13C, 29Si, 119Sn, 19F, 7Li, 31P, 11B
