On enhanced translational diffusion or the fractional Stokes-Einstein relation observed in a supercooled ionic liquid
Article Abstract:
The enhanced translational diffusion or fractional Stokes-Einstein and fractional Debye-Stokes-Einstein relation observed in the supercooled molecular ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate (BMIM-HFP) are reported. The coupling parameters of all processes are known including that of translational-rotational diffusion, thereby presenting an opportunity for critically testing the Coupling Model explanation of the observed fractional Stokes-Einstein and fractional Debye-Stokes-Einstein redlations.
