Paper Abstract

The hydrogen bonding in water and 2M aqueous solutions of NaCH3COO, (CH3)4NCl, NaCl and NaCSN was studied by Raman spectroscopy of the vibrationally decoupled O-D stretching band of water. The isotropic O-D stretching spectra were modeled by means of Gibbs' statistical ensembles of hydrogen bonded oscillators. The thermodynamical parameters of the ensembles were estimated. They were related with properties of the hydrogen bond network in water. It was revealed that the salts break the structure of water reducing the strength of hydrogen bonding. According to their influence on the strength of hydrogen bonding the salts can be arranged in a series similar to the Hofmeister series of salts.
