摘要：

In H,H COSY spectra of rigid cyclic terpenes, many long-range couplings can be observed. The coupled nuclei are connected either by a zig-zag coupling path or they are close in space. The latter are called 'through-space' coupling. A certain stereospecific relationship between the coupling partners is necessary. This phenomenon is in accordance with the theoretical explanations.
