Geometrical isomers of methyl 9,12,15‐octadecatrienoate were subjected to alkali isomerization according to the official AOCS method. The c,t,t and t,t,c isomers gave higher specific extinction coefficients at 268 mμ than the all‐ cis isomer. The all‐ trans isomer was not completely conjugated. These results are in conformity with previous predictions based on theoretical and experimental evidence.
