## Abstract The proton‐coupled ^13^C NMR spectra of 1‐__trans__‐methoxy‐ (2) and 1‐__cis__‐methoxy‐1,3‐__trans__‐butadiene (3) are consistent with a methoxy heavy atom planar conformation with __s‐syn__ and __s‐anti__ orientations, respectively. __Ab initio__ 6–31G\* calculations confirmed such con

The proton spectrum of the isomeric mixture of &,cis-and cis,trans-1,3,5-triamino~clohexane was assigned with a 2D COSY experiment. Using Forrest's modified equation and the 2D J spectrum results, the conformations of the two isomers were analysed. The six-membered ring of the cis,trans isomer is fl
