Ew. Castner et al., FEMTOSECOND FOURIER-TRANSFORM SPECTROSCOPY OF LOW-FREQUENCY INTERMOLECULAR MOTIONS IN WEAKLY INTERACTING LIQUIDS, Journal of luminescence, 60-1, 1994, pp. 723-726
We present new results on the temperature-dependent collision-induced
low-frequency Raman spectrum of the spherical top molecule CCl4, obtai
ned using optical-heterodyne-detected, femtosecond Fourier-transform R
aman-induced Kerr-effect spectroscopy. A spectral shift to lower frequ
encies with increasing temperatures has been observed.
