Abstract
The IR spectra of 1:1 and 1:2 complexes of dichloro-substituted anilines with various proton acceptors have been investigated and the parameters of the absorption bands of the stretching and deformation vibrations of their amino group have been determined. Vibrational and electro-optical problems have been solved for free and H-bonded molecules of the studied amines within the framework of the R-NH2 model of a valence-free field. The geometric, dynamic, and electro-optical parameters of the amino group of dichloro-substituted anilines in complexes of different compositions have been determined. It is shown that the hydrogen bond in 1:1 complexes appears to be stronger than in 1:2 complexes.
