摘要：

Terahertz time-domain spectroscopy is used to investigate the dielectric relaxation properties of liquid CS2. The frequency-dependent absorption coefficient and index of refraction were measured in the frequency range 0.2-2.0 THz. The ultrafast dielectric relaxation time of liquid CS2 was determined to be 630+/-30 fs by fitting the dielectric function to the Debye model which is attributed to average time for rocking and rotational response of the CS2 molecules possessing an anisotropic polarizability.
