- Аннотация: Analysis of carotenoid content and isomeric states is of great interest for medicine, pharmaceutical, cosmetic and food industry. In particular, cis-isomerization of carotenoids would probably influences the provitamin A activity, skin protection and anticancer effects. Resonance enhancement of Raman intensity allows to study carotenoids at very low concentrations. The aim of this work was to reveal differences in Raman spectra of various carotenoids and their isomers, using the DFT calculation. We concluded that the peak positions and intensities of the carotenoid Raman bands, related to the stretching vibrations of single and double C-C bonds, depend on the length of polyene chain, on the number of ionone rings, and type of the isomer.
