摘要：

This study is devoted to the investigation of the influence of micellization on structure properties of water and to micellization-induced liquid-liquid fluctuations in sodium dodecyl sulfate aqueous solutions. The dependence of Raman spectra of SOS aqueous solutions on surfactant concentration has been studied. Significant changes in the dependences of water valence band characteristics at the moment of micellization have been observed. Precision analysis of valence bands with the multivariate curve resolution-alternating least squares (MCR-ALS) method has confirmed these results. The observed structural changes in water are interpreted as significant fluctuations of the sizes of populations of LDL-rich and HDL-rich clusters of water. (C) 2015 Elsevier B.V.
