Abstract :
Light scattering studies of water properties in aqueous solutions of polyoxyethylene non-ionic amphiphiles C E and methanol are presented. Depolarized Raylegh spectra are studied to obtain the rotational relaxational time of water, whereas Brillouin scattering is used to have details on the sound propagation. The systems are studied for different temperatures and concentrations. Data analysis reveals that the solutes (amphiphile and alcohol) molecular head groups (hydrophilic and hydrophobic) have relevant effects on the water dynamics and structure.
