Introduction,ower of the technique is far greater than as a replacement for elemental analysis and indeed can be used to solve complicated structural problems more readily than less straightforward methods such as 2-D . H NMR. techniques.

Bicyclooctanes,Stereochemistry for the cis-fused series in this system is readily specified by exo and endo. While there are two, relatively conformationally mobile rings present, this sytem is especially well behaved in terms of shift additivity. No significant quantity of data was found for trans-fused bicyclooctanes.
