FTIR studies of the structure of water in salt solutions

The DOH system in H₂O and 2 M aqueous salt solutions of NaSCN and (CH₃)₄NCl has been studied by the fluctuation model of hydrogen bonding. A number of quantitative parameters, characterizing the hydrogen bond network of the DOH system has been derived. The salts have an influence on the structure of the solutions in accordance with their positions in the Hofmeister series. A simple and efficient procedure for evaluation of the thermodynamical parameters of water solutions is described and verified. The specific heat values C_V of the studied solutions are determined by means of the statistical integral Z(T). The values coincide very well with literature data.
