We report on the possibility of extracting fast dynamical relaxation times from homodyne transient grating measurements. We demonstrate the validity of our approach by experimental measurements on liquid acetonitrile and by comparison with literature. This approach would be of tremendous help in the case of free-electronlaser-based transient grating experiments due to the overcoming of technical difficulties, such as large-angle geometries.
