ABSTRACT
UV-vis spectral parameters are predicted for fourteen (Z) 2-(2-hydroxy-2-phenyl-vinyl)pyridines being in the tautomeric equilibrium with 2-phenacylpyridines (solutions I chloroform). Evaluation of the band intensities is based on content of the enolimine form determined by 1H NMR spectroscopy. Effect of the substituent on both position and intensity of the absorption band as well as on tautomeric equilibrium is discussed.
