title: Mediating relaxation and polarization of hydrogen-bonds in water by NaCl salting and heating.
abstract: Infrared spectroscopy and contact-angle measurements revealed that NaCl salting has the same effect as heating on O:H phonon softening and H-O phonon stiffening, but has the opposite effect on skin polarization of liquid water. The mechanics of thermal modulation of O-O Coulomb repulsion [Sun, et al., J. Phys. Chem. Lett., 2013, 4, 3238] may suggest a possible mechanism for this NaCl involved Hofmeister effect, aqueous solution modulated surface tension and its abilities in protein dissolution, from the perspective of Coulomb mediation of interaction within the O:H-O bond.
