UV photoelectron spectroscopic study of substituent effects in quinoline derivatives

摘要: The molecular and electronic structure of eight substituted quinolines has been investigated by HeI/HeII photoelectron spectroscopy, Green's function calculations, comparison with the spectra related compounds. correlation between nitrogen lone pair ionization energies basicity in 18 is discussed. influence different substituents quantified via scheme that based on experimental energy shifts. relationships energies, pK(a) values, medicinal activity are also
