Experimental observations of vibrational spectra of strong electrolyte solutions with increase in the molarity suggest a self-organization of water molecules depending on the concentration, and not on the ions’ nature. Three different regimes can be observed. At very low concentrations, ions shielding does not change the water molecules intramolecular bonds. Whenever the concentration increases, a distortion of the vibrational peak is observed that increases linearly on a log-log scale, and can lead up to a maximum deformation limit. This might contribute to shed a light on the nature of the two-fluid structure of liquid water reported in the literature. © 2018 Elsevier B.V.
