โœฆ Synopsis

Sixth moments of Rayleigh spectra of fluid Nz are measured over a wide range of thermodynamic states. It is argued that induced contributions affect sixth moments mainly through terms involving potential derivatives explicitly. An empirical time, independent of density, can be tentatively related to an effective duration of collisions.

Isotropic and anisotropic Rayfeish spectra of fluid N2S are reported. Collision-induced rotational smttering contributions are considered to explain the spectral features. It is argued that isotropic spectra arc mainly due to the dipole-quadrupole polarizability at h&h frequency while the first hype
