Abstract

Temperature-dependent molecular dynamics of CS₂ liquid are examined in femtosecond time-resolved impulsive stimulated scattering experiments. At temperatures T≤ 240 K, weakly oscillatory time-dependent responses are observed. These are interpreted in terms of librations of molecules about their local potential minima. The librations undergo rapid inhomogeneous dephasing. Temperature-dependent values of the configuration-averaged librational frequency and the extent of inhomogeneity in that frequency are determined.
