title: Spectral analysis and high-performance liquid chromatography of the cis-trans geometrical isomers of 5,6-Epoxyretinal.
abstract: Spectral characterization of 5,6-epoxyretinal isomers (II) prepared by a regioselective epoxidation of the parent retinal isomers have been described. High-performance liquid chromatographic separation of epoxyretinals and a photoisomerization behavior of all-trans-5,6-epoxyretinals (IIa) have been investigated.
