Abstract

Terahertz (THz) spectroscopy has emerged as a powerful tool for characterizing materials across a wide range of scientific fields, including chemistry, biology, and materials science. Operating in the frequency range of 0.1 to 10 THz, this technique provides unique insights into molecular vibrations, rotational modes, and electronic transitions. This article reviews the principles and methodologies of THz spectroscopy, detailing its various applications in material characterization, chemical sensing, and biomedical imaging. Challenges associated with the technique, such as sensitivity and resolution limitations, are discussed, along with advancements that aim to overcome these obstacles. The future of terahertz spectroscopy, including potential innovations and interdisciplinary applications, is also explored. By presenting a comprehensive overview, this article highlights the significance of THz spectroscopy in advancing both fundamental and applied research.
