Temporal Behaviours of Stimulated Rayleigh-Wing Scattering atNon- and Quasi-Equilibrium of Orientational Distribution

The temporal behaviours of stimulated Rayleigh-wing scattering, at quasi-equilibrium and non-equilibrium of the molecular orientational distributions, are reported in this letter. The experimental results also show the relaxation time of molecular orientation in high alignment is longer than 80 picosecond.
