Vibrational spectra, structures, and conformations of conjugated azomethines ? 3-imidazoline derivatives

Abstract

The possibility of the use of the ratios of the intensities of the v C=N bands in the Raman spectra of the compounds to establish the conformations of the conjugated C=N bonds was demonstrated in the case of conjugated azomethines — derivatives of 2,2,5,5-tetramethyl-3-imidazoline and — 3-imidazoline 3-oxide.
