WebApr 5, 2024 · We report the dynamics of concentrated lithium chloride aqueous solutions over a range of moderate to high concentrations. Concentrations (1-29 to 1-3.3 LiCl-water) were studied in which, at the highest concentrations, there are far too few water molecules to solvate the ions. The measurements were made with optically heterodyne-detected … WebFeb 16, 2016 · This has made Raman spectroscopy an extremely powerful technique for probing nascent symmetry and symmetry changes induced by internal or external perturbations. ...
