Abstract

• We describe ail experimental Study Of the dynamic structure factor of liquid glycerol performed by complementary inelastic techniques Such as Brillouin visible, ultraviolet and x-ray scattering. The spectra have been collected as a function of both temperature and momentum transfer. The relevant hypersonic parameters are evaluated from the spectral lineshape analysis modelling the data with a simple hydrodynamic profile. The Study of their frequency dependence allows us to observe the Occurrence of ail active structural relaxation and to measure the related timescale. We also find signatures of further relaxation processes occuring below the accessible frequency window. As a result, the dynamic window traditionally probed in spectroscopic experiments is greatly extended and partially bridges the gap between MHz and THz techniques. (literal)
