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 C1EnE1 (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 C1EnE1 (n=1-4) at different concentration showed that the water structure is influenced in a similar way in the case of C2E2C2 and of C1EnC1.
