The Variation of the Raman Spectrum of Nitrate Solutions with Cation

摘要

The strong Raman line from solutions of cadmium, silver and lead nitrates has been remeasured at varied concentrations, and the results of Grassmann confirmed, namely that the frequency shift diminishes with increasing concentration for lead and silver, and varies little for cadmium. A qualitative explanation of this behavior and that of sodium nitrate is suggested in the effect of the cations on the structure of water, and attention is drawn to the similar order of these nitrates in xhyphen;ray diffraction phenomena.
