Abstract The concentration dependences of self-diffusion coefﬁcients of water and
ethanol molecules in water–ethanol solutions are obtained by the method of nuclear
magnetic resonance spectroscopy with the pulse magnetic ﬁeld gradient. On the
basis of the ideas of hydration of ethanol molecules, the obtained dependences are
interpreted and assumptions are made about the structural organization of water–
ethanol solutions in the region of diluted and concentrated solutions.
It is difﬁcult to argue that starting a study of any molecular systems, in which water
is one of the main components, the system under investigation will behave in a
manner different from the manner assumed on the basis of the vast amount of
previous knowledge about the properties of similar systems. In the attempt to use
the approaches we applied during the study of the water solutions of glycols and
saccharides, these approaches were not effective when applied to water solutions
containing ethanol as a component.
To solve these problems, we undertook a special study of the ethanol solutions.
We realized that water–ethanol solutions were investigated many times in different
aspects and a vast amount of experimental results about the properties of these
solutions was accumulated. A comparative analysis of physicochemical, thermo-
dynamic properties of different water–alcohol mixtures including also water–
ethanol solutions and their anomalies was carried out in a fundamental work .
