Coherent two-dimensional terahertz-terahertz-Raman spectroscopy [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance The thermally populated motions of liquids, including hydrogen bonds, low-energy bending vibrations, conformational torsions, and hindered rotations, are resonant in the terahertz region of the spectrum. These motions regulate solvation, macromolecular structure, and vibrational energy flow in liquid-phase chemistry.
