| Abstract Scope |
Over the past two decades, terahertz time-domain spectroscopy has become a key technique for characterizing solid samples due to its sensitivity to bulk molecular packing and ability to probe weak forces and long-range molecular dynamics. This makes it powerful for studying crystalline polymorphism and other condensed phase properties. Recent studies reveal terahertz vibrations are crucial for many physical phenomena, from thermomechanical properties to solid-state phase transformations. In this work, terahertz spectroscopy examines several solid-state materials, determining their elastic responses, deformation pathways, and polymorphic transitions. The technique is particularly valuable for exploring the intermolecular coordinate in condensed phase materials. Overall, this work emphasizes the significant role of low-frequency vibrational spectroscopy in understanding the properties of advanced organic materials. |
