THz Time Domain Coherent Raman Spectroscopy for Liquid Samples

摘要

Aiming for observation of low-frequency vibrations of bio-molecules, we havedeveloped terahertz (THz) time-domain coherent Raman spectroscopy. In this THztime-domain coherent Raman spectroscopy, two frequency chirped femtosecond pulsesare used to generate THz optical beat in the sample. In this paper, we report the result ofobservation of some organic liquids to confirm the performance of our spectroscopicsystem for liquid samples. The results of inverse Raman spectra for iodobenzene andbromobenzene are presented.
