Terahertz radiation can probe rotational translations, low-frequency bond vibrations, crystalline phonon vibrations, hydrogen-bond stretches, and torsional vibrations within a material . Similar to low frequency Raman scattering, neutron scattering and light scattering techniques which cover a range of energy, frequency, and timescales, photon energies oscillating at terahertz frequencies (0.1 3 THz) can excite low energetic intermolecular interactions of materials, including phonon modes and hydrogen bond vibrations . Recently, terahertz time-domain spectroscopy (THz-TDS) has been used to investigate the dynamics of the aqueous hydration shell of proteins at the terahertz region . This is possible since the dielectric response corresponding to the reorientation of water dipoles has been shown to occur on picosecond timescales in the terahertz region .
