  1. 1.

    A study of the concentration dependences of the chemical shifts of hydrogen chloride in various electron-donor solvents indicates the formation of an intermolecular hydrogen bond between the HCl and solvent molecules.

  2. 2.

    The composition and structure of the donor-acceptor complexes formed depend on the ratio of the HCl and solvent (P) concentrations. If [HCl] ≫ [P], then the polymer autoassociate [HCl]n predominates in solution; if [HCl] = [P], the main component of the solution is the oligomer complex mP·(HCl)m; if [HCl] ≪ [P], monomer complexes P · HCl predominate in solution.

  3. 3.

    The strength of the intermolecular hydrogen bonds formed in the complexes mP · (HCl)m is characterized by the depth of the plateau of the experimental curves, while for the complexes P. HC1 it is characterized by the extrapolated chemical shift with decreasing HC1 concentration.
