Popis:	IR, PE, 1 H-NMR and UV/Vis spectroscopy were used to study the conformation of capsorubin and isomers. The four isomeric capsorubins behave spectroscopically different in dependence of the stereochemistry of OH group. A strong hydrogen bond between OH and the n orbital of the carbonyl group determines the conformation of the capsorubins with cis stereochemistry at the end groups. This interaction influences all spectroscopic properties, particularly the ππ ★ transition energies.
