Goal

Although coupling constants - and indirectly multiplicities - provide essential information on the spatial structure of a molecule, their evaluation is sometimes somewhat neglected. Mathematically, it is a simple difference, but it is not necessarily easy to extract from complicated coupling patterns. As with nuclear magnetic resonance spectra in general, it is a matter of recognising and analysing patterns. The examples in this section are mainly devoted to this topic and to a systematic approach to resolving even complicated multipletts.
