In very concentrated aqueous electrolyte solutions, the competition between dipolar and ionic forces and most of the system properties, are finely monitored by the concentration. For LiCl, RH 2 O (R being the number of water moles per mole of salt) two domains of concentration exist around even hydration numbers R=6 and R=4, which can be reversibly undercooled from the liquid to the glassy state. At other concentrations, for R<12, metastability is achieved only in a restricted temperature range…

TLDR
The authors' data show that a single-relaxation process exists at high temperature, which has features similar to those of the single relaxation of pure water, and which starts to differentiate two processes, a structural (alpha-) and a secondary (beta-) relaxation.
