NMR spectroscopy: quantum-chemical calculations

The first-principles computation of nuclear magnetic resonance parameters, in particular chemical shift and spin-spin coupling tensors, is reviewed. After a brief nontechnical introduction into the methodology behind such calculations, selected applications from chemistry and biochemistry in solution and the solid state are highlighted. Special attention is called to cases wherein theory can help in structure determination and refinement, as well as in the interpretation of the observables. (C) 2011 John Wiley & Sons, Ltd.
