Abstract

The asymptotic decay time τ_an of the anisotropic vibrational excitation in liquids has been measured for the first time in time-resolved CARS. The use of different polarization geometries also allows us to determine the orientational relaxation time τ_R. Experimental data are presented for totally symmetric modes of liquid CS₂ and CH₃I, where τ_R describes the "tumbling" motion of the symmetry axis.
