Title:ULTRAFAST TERAHERTZ KERR EFFECT SPECTROSCOPY OF AROMATIC LIQUIDS

Abstract:Ultrafast Terahertz Kerr Effect (TKE) spectroscopy is a relatively new nonlinear THz technique that is sensitive to the orientational dynamics of anisotropic, condensed-phase samples. The sample is excited by a single high field strength $sim$1 picosecond THz pulse, and the resulting transient birefringence is measured by a $sim$40 femtosecond 800 nm probe pulse. We have measured the TKE response of several aromatic liquids at room temperature, including benzene, benzene-d6, hexafluorobenzene, pyridine, and toluene. The measured decay constants range from $sim$1-10 ps, and, along with previous optical Kerr effect results in the literaturefootnote{Loughnane et al. JPCB 110.11 (2006): 5708-5720.}, give insights into intermolecular interactions in these liquids.
