Effect of microscopic NaCl impurities on clustering dynamics in liquid water: low-frequency Raman spectroscopy
Baranov A. V. , Petrov V. I. , Fedorov A. V. , Chernyakov G. M.
The temperature dependence of the characteristics of the elastic-vibration band of water clusters in the spectra of low-frequency Raman scattering of water and aqueous solutions of NaCl has been studied. The size of the clusters is estimated as a function of the temperature (0-99 °C). The NaCl has a pronounced destructive effect on the clustering process even at a concentration of 10~5 M. This effect apparently occurs only above a threshold concentration. This threshold may be considerably lower than the concentrations used in these experiments.
