Abstract

We have measured the viscosity η and the frequency-dependent shear modulus of the glass-forming liquid di-η-butylphthalate. Both η and the shear relaxation time τ have non-Arrhenius dependence on temperature T. The ratio ητT is weakly T dependent implying a slight deviation from the Einstein-Debye equation. This is fully explained by a smooth evolution of the relaxation spectrum and is not accompanied by growth of the elastic shear modulus or a correlation length, as had been suggested.
