We have determined enthalpy and entropy of activation and FT-IR spectra of the four thermally labile isomers of retinal (11,13-dicis, 7,11,13-tricis, 9,11,13-tricis, and all-cis). The data are in agreement with the postulated Kluge-Lillya mechanism of isomerization, involving consecutive 6e-electrocyclization reactions for the stereospecific reactions.
