Abstract: The transient grating experiment is a very useful spectroscopic tool to investigate glass-former and viscous liquid dynamics. The technical improvements, introduced in the recent years, transformed it in a unique spectroscopic technique, thanks to the wide time window covered and the quality of experimental data. Furthermore, only recently a precise definition of the measured response function has been obtained permitting a more exact description of several dynamical processes present in complex liquids. In this chapter we review the transient grating spectroscopy from both experimental and theoretical points of view, paying particular attention to the interpretation of the measured data.
