Nuclear magnetic resonance spectroscopy is a highly advanced molecular spectroscopy technique used for the structural analysis of molecules, generating the molecular fingerprint of a molecule under investigation by irradiating the sample in a strong magnetic field using high-frequency pulses. 

This allows, for example, the result of a complex organic synthesis to be checked and confirmed with regard to important parameters such as structure, isomerism, stereochemistry or even spatial structure. NMR spectroscopy is therefore an integral part of the modern research and development landscape of active and effect substances of all kinds.
