Abstract

Previous studies of OH stretching band of aqueous solutions of short poly(oxyethylene)s POEs showed similarities between ratios R of the intensities of the component around 3200 cm^-1 (the collective in-phase OH stretching vibrations of hydrogen-bonded aggregates) and the component around 3400 cm^-1 (the out of phase OH stretches) in dependence on type and concentration of dissolved POEs. According to previous studies on C₁E_nE₁ (n=1-4) the intensity ratio R is characterized with two minima. We observed the same behavior in the case of C₂E₂C₂. In addition the perfect match of the spectra of C₂E₂C₂ and those of C₁E_nE₁ (n=1-4) at different concentration showed that the water structure is influenced in a similar way in the case of C₂E₂C₂ and of C₁E_nC₁.
