Terahertz spectroscopy refers to spectroscopic techniques that probe materials using electromagnetic radiation in the terahertz (THz) region, typically from ~0.1 to 10 THz (3 mm–30 μm). THz spectroscopy accesses low-energy excitations such as rotational and vibrational transitions in molecules, phonons and collective modes in solids, charge transport in semiconductors and superconductors, and intermolecular interactions in liquids and biomaterials.
