Abstract
The theoretical background of ''anomalous'' splitting of signals of mo lcular fragments -CH=CH- in off-resonance decoupled C-13 NMR spectra i s described. The use of these splitting phenomena on the determination of vicinal H,H and geminal C,H coupling constants is demonstrated usi ng simple examples. The possibilities to determine the configuration o f double bonds are shown by other examples from the field of natural c onstituents chemistry.
