Abstract
Abstract The UV spectra of 2-iodopicolines, their N -oxides and 2-iodo-4-nitropicoline N -oxides in ethanol have been examined and compared with the results (transition energies, intensities) of modified INDO calculations in order to make the assignment of allowed bands. The influence of substituents on the molecule on λ max and ϵ max of spectral bands is discussed. The electronic spectra of 2-iodo-3-methyl-4-nitropyridine and 2-iodo-5-methyl-4-nitropyridine N -oxides and the effect of steric hindrance on the spectra are interpreted.
