The dynamical response of matter measured by femtosecond optical Kerr effect spectroscopy is directly compared with the high-resolution light scattering spectrum obtained by a tandem Fabry-P\'erot interferometer. Using simple liquids as samples, we have for the first time confirmed experimentally that the material responses obtained by these time- and frequency-domain measurements completely agree with each other in a frequency region extending over 3 orders of magnitudes.
