title: Librons observed in liquid acetonitrile by hyper-rayleigh scattering
abstract: Hyper-Rayleigh scattering intensity ratios I(VV)/I(VH) in the range 9-26 are observed for liquid acetonitrile (CH 3CN), inconsistent with localized modes of motion in an isotropic fluid. The observations are consistent with propagating orientational modes (librons) with frequency nu = 2 cm (-1), which scatter 71% of the light.
