Abstract
Quantitative results for the separate temperature and density effects on collision-induced scattering (CIS) line shapes for the dense molecular fluid CS2 are presented for the temperature range T=293–353 K and density range ρ=1.25–1.48 g cm−3. The depolarized Rayleigh scattering (DRS) and ν1, ν2, and ν3 mode Raman scattering line shapes are specifically investigated. The three distinctive CIS line shape regions observed, corresponding to low, intermediate, and high frequency line shape ranges, are interpreted qualitatively in terms of available theoretical models. The results generally support the multipole–induced-dipole interaction mechanism for all CIS line shapes at all frequencies, and the dominance of translational over orientational dependence of the induced dipole moment at intermediate and high frequencies of CIS line shape.
