Terahertz time-domain spectroscopy (THz-TDS) is a powerful analytical technique used to study materials in the terahertz (THz) frequency range, which generally spans from about 0.1 to 10 THz (or 0.1 to 10 THz = 0.1 to 10 x 10¹² Hz). This method provides information about the electronic, vibrational, and rotational dynamics of both solid and liquid materials.
