Normal‐coordinate calculations have been performed for the all‐ trans , 9‐ cis , 11‐ cis and 13‐ cis isomers of retinal using a model structure in which the β‐ionone ring was replaced with a simplified structure. Most of the Raman and infrared bands observed from these isomers in the solid state are assigned on the basis of the results of calculation. The vibrational characteristics of each isomer are discussed.
