Paper Abstract

Previous studies of OH stretching band of aqueous solutions of short poly(oxyethylene)s POEs showed a 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. In this paper we checked how the hydration structure of water molecules around four types of short POE - C1EiC1 (i=1,2,3,4) aqueous solutions depends on the length and the type of the dissolved POE.
