Abstract
Combined approach to analysis of 2-allylthioquinoline and 2-ethylthioquinoline solutions has been performed on the basis of UV-Vis spectroscopy. Experimental and calculated electronic absorption spectra of these compounds in various solvents: acetone, benzene, carbon tetrachloride, dichloromethane, ethanol have been considered. The negative solvatochromic effect has been observed. The results of our calculations have revealed that the spectra of various conformers of 2-allylthioquinoline differ more essentially than the spectra of 2-ethylthioquinoline conformers. It has been shown that the location of λ max band doesn’t drastically depend on allyl or alkyl substitution at the sulfur atom.
