Abstract
Time-domain light scattering experiments on ps-μs time scales have been conducted on a concentrated aqueous LiCl solution. Analysis of mechanical and electrical modulus spectra confirms some results of mode-coupling theory: Simple scaling for α peaks and property-independent power laws. This is made without any assumptions about the data which are not derived from theory. A new characteristic time scale, reflecting the short- and intermediate-range ordering dynamics, is also observed.
