Abstract
The frequency dependences of the shear modulus, G(s)(omega), (10 Hz-60 kHz) and dielectric constant, epsilon(omega), (10 Hz-10 MHz) have bee n measured at various temperatures. Two different liquids have been st udied: the polyalcohol 1, 3-Butandiol which has a large dielectric rel axation strength and a silicone oil with a very small relaxation stren gth. It is shown that the normalized relaxational part of the inverse dielectric susceptibility and the mechanical shear modulus are identic al for both liquids, while the loss peak frequencies are different.
