    Dipole Moments and Spectral Features of Some Phenol-Diethylamine Complexes
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1981, 77 (06), 1981) Oszust, Jadwiga; Ratajczak, Henryk
    The dipole moments of molecular complexes of two types, AB and A2B2, formed between phenol derivatives with diethylamine in benzene solution have been determined. The polarity of the hydrogen bond, Δµ, in AB complexes depends on the pKa of the phenol and confirms the generality of the Δµ against pKa sigmoid curve. A2B2 complexes change their structure from chain to cyclic when the proton-donor properties of the phenol increase.

    Study of the Equilibria in Some Diethylamine-Phenol Molecular Complexes in Aprotic Solvents
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1981, 77 (06), 1981) Oszust, Jadwiga; Ratajczak, Henryk
    Molecular associations in systems consisting of phenol derivatives with diethylamine in benzene solution have been studied by cryoscopic and dielectric methods. Over the concentration range studied the AB and A2B2 species dominate in solution. The equilibrium constants have been determined in CCl4 by infrared spectroscopy.
