The stereochemical dependence of the vicinal 13C14N coupling constant as a constitutional probe

The magnitudes of 13C14N coupling constants have been measured in 12 rigid or anancomeric (biased) tetraalkylammonium iodides. The one-bond coupling is typical for the degree of substitution of the carbon atom and the geminal coupling is very small. Vicinal couplings depend on the dihedral angle and other factors.
