Abstract
An all-trans carotenoid, because of its nearly coplanar chromophore and perfect resonance, is generally expected to surpass in stability its cis isomers. Nevertheless it should be pointed out that simple characterizations such as “stable” or “labile” have lost much of their meaning in the class of multiconjugated systems. Because the degree of the double bond character is subject to considerable variation along the chain, the extent of liability of a given steric form depends not only on the number but also on the location of cis double bonds, hence on the overall shape of the molecule.
