Carbon‐13 NMR spectra have been obtained for all‐ trans ‐ N ‐retinylidene‐ n ‐butylamine as an analogue of the Schiff's base linkage compound in visual pigment. The chemical shift changes on going from all‐ trans ‐retinal 1 to all‐ trans ‐ N ‐retinylidene‐ n ‐butylamine are observed. These changes indicate the collapse of the bond alternation in conjugated polyene carbons, whereas N‐protonation in all‐ trans ‐ N ‐retinylidene‐ n ‐butylamine does not affect the bond alternation.
