The inelastic scattering of light arising from the time-dependent polarizability induced by intermolecular interactions has been observed in the simple classical liquid, argon. The spectrum at 90 \ifmmode^\circ\else\textdegree\fi{}K and 1.5 atm is centered at zero frequency shift, and is exponential in shape, with a characteristic width of 21 . The depolarization ratio for the scattered light is 0.72 \ifmmode\pm\else\textpm\fi{} 0.02, implying that the anisotropy
