## Abstract A series of alicyclic compounds with dihedral angles of 0°, 60°, 90°, 120° and 180° between a ^13^C‐labelled carbon atom and a carbon atom separated by three bonds from the label has been synthesized. The vicinal ^13^C^13^C spin coupling constants were measured, and from the results a K
