NMR

NMR spectroscopy has become one of the most important instruments in the field of structure determination of a wide variety of compounds. For example, NMR spectroscopy cannot only be used to determine molecular structures but also to get informations about the identity and purity of substances, molecular conformations and intermolecular interactions. Generally speaking, the method serves to investigate the electronic environment of individual atoms and thus provides insight into the interactions between neighbouring atoms. However, certain factors such as the solubility of the sample, the water content and viscosity of the solvent as well as the position of the solvent signals in the spectrum have to be taken into account, when selecting a suitable solvent.
