15 N chemical shifts, 1 J (NN), 1 J (NC) and 2 J (NC) coupling constants have been used to prove the open chain structure and configuration of cis ‐ and trans ‐2,3‐diphenyl‐1‐phthalimidoazimines. For comparison, the corresponding data of the iso‐π‐electronic cis ‐ and trans ‐azoxybenzenes are also reported and discussed.
