Figure 4
Dispersion relation (symbols) of the relaxation rate [\Gamma]. The dotted line is the prediction for the systems at infinite dilution (i.e. undergoing free Brownian motion) with the proportionality factor being the Stokes–Einstein diffusion constant D0Th = 1.29×10-17 m2 s-1. The solid line is a fit to the data assuming a Q2 `parabolic' behavior. It gives the self-diffusion constant DSexp = 7.5×10-18 m2 s-1. The dashed line is the predicted dispersion using equation (8)[link], giving DSTh = 1.08×10-17 m2 s-1.
