Abstract

The biological, pharmaceutical, medicinal and therapeutic properties of vitamins make the investigation of solvatochromic interactions between vitamin molecules and their surroundings to play an important role in biological systems. The presence of multiple groups of vitamins A and B makes difficult to predict the photo-physical behavior. For more study in this experimental work, absorption and fluorescence spectra of some vitamins A and B groups were recorded in different solvents with various polarities in the range of 300-800 nm. The obtained results indicate that photo–physical behavior of solute depends strongly on the nature of the solvent and solute, the solvent–solute interactions, and different attached groups on their structures. For understanding the solvent effect on spectral behaviors of these vitamins, nature, and extent of solvent–solute interactions, the spectral variations were analyzed by means of linear solvation energy relationships concept proposed by Kamlet and Taft. The obtained results can give important information on how this group of vitamins behaves in biological systems.
