Electrolyte Solvation and Ionic Association. VII. Correlating Raman Spectroscopic Data with Solvate Species
Wesley A. Henderson, Daniel M. Seo, Sang‐Don Han, Oleg Borodin
Abstract
Raman spectroscopy is a widely utilized method for determining information about the solvate species present in electrolyte solutions. Difficulties arise, however, when interpreting the Raman data in terms of correlating the spectroscopic vibrational bands with specific solvate species. Examples are provided to demonstrate how erroneous conclusions may be drawn with regard to the identity and population (distribution) of the solvent-separated ion pair (SSIP), contact ion pair (CIP) and aggregate (AGG) solvate species frequently mentioned in the scientific literature.
