title: Experimental study on the relationship between the frequency-dependent shear viscosity and the intermediate scattering function of representative viscous liquids.
abstract: The frequency-dependent shear viscosity of two representative viscous liquids, o-terphenyl and glycerin, was experimentally determined at several temperatures and compared with the intermediate scattering functions reported in the literature. A comparison based on mode-coupling theory succeeded in relating the frequency-dependent shear viscosity with the intermediate scattering function at the main peak of the static structure factor. It suggests that the slow relaxation mode of the shear viscosity of both liquids is governed by the density fluctuation at the main peak of the static structure factor, in spite of the differences in the details of their intermolecular interactions.
