Abstract

The structure of water in aqueous solutions of polyoxyethylene nonionic amphiphiles C10E5 is studied by Raman scattering along an isothermal path crossing the isotropic one-phase region from 0 to 1 amphiphile volume fraction φ. The isotropic OH stretching vibration spectrum evidences a behavior that depends on the amphiphile concentration. The interpretation of such scattering data leads to the following structural picture for the water in the systems; for φ lower than 0.75, water is partially bound to the oxyethylene groups of the amphiphile; above φ=0.75 all water present in the system is bound. The structure of such bound water presents a local, low dense, four coordinated environment.
