Theoretical Studies of Milk: Solvent Effects on the Molecular Properties of Retinoid Compounds

Abstract
We discuss here the role of environment in the structural and spectroscopic properties of vitamin A in its retinoid forms: retinol and retinal. The analyzed compounds show three singlet excited states exhibiting wavelengths between 472 and 273 nm according to the medium. The transitions involve HOMO, LUMO, HOMO-1, LUMO and HOMO, LUMO+1 orbitals.
