Abstract

In this talk, we will report on terahertz (THz) time-domain coherent Raman spectroscopy developed for investigation of low-frequency molecular vibrational modes. The unique properties, as well as the principle of this technique, are explained. This method is simple and useful to study low frequency (< 20 THz) atomic and molecular dynamics in solids, liquids and aqueous solutions, in particular, for observation of picosecond molecular dynamics and weak molecular interactions, such as hydrogen bonding. Several examples of coherent Raman spectra measured with this technique, such as water solution of TMAO molecule, are presented.
