摘要
Kinetics of the decay of transient gratings (four-wave non-simultaneous interaction) in nitrobenzene liquid in the femtosecond time scale is studied. Experimental results are explained in terms of coherent vibrational molecular motion in liquid. A strong dependence of the kinetics of the signal decay on the polarization of the probe field is discovered The beats of underdamped vibrational modes of nitrobenzene are separated.
