title: Data from: Transition from fractional to classical Stokes-Einstein behaviour in simple fluids

description: An optical technique for tracking single particles has been used to
 evaluate the particle diameter at which diffusion transitions from
 molecular behaviour described by the fractional Stokes-Einstein
 relationship to particle behaviour described by the classical
 Stokes-Einstein relationship. The results confirm a prior prediction from
 molecular dynamic simulations that there is a particle size at which
 transition occurs and show it is inversely dependent on concentration and
 viscosity but independent of particle density. For concentrations in the
 range 510-3 to 510-6mg/mL and viscosities from 0.8 to 150 mPa s, the
 transition was found to occur in the diameter range 150 to 300nm.
