低频振动光谱学领域在过去的二十年中有了显着的发展，这是基于实验激光器和光学的进步，以及高性能计算和量子力学模拟。这些技术的结合使人们能够前所未有地深入了解太赫兹频率下发生的原子级动力学，这通常涉及整个分子的大幅度运动。这最终为社区提供了新的工具，通过对分子间力和动力学的理解来研究和设计晶体材料。在本观点中，将提供该领域的概述，并通过最近的例子进行补充，其中低频振动运动被用于理解和驱动散装材料功能。
The field of low-frequency vibrational spectroscopy has grown significantly over the past two decades, based on advances in both experimental lasers and optics, as well as high-performance computing and quantum mechanical simulations. The combination of these techniques has enabled unprecedented insight into the atomic-level dynamics that occur at terahertz frequencies, which usually involve large-amplitude motions of entire molecules. This has ultimately provided the community with new tools for investigating and engineering crystalline materials through an understanding of intermolecular forces, as well as dynamics. In this Perspective, an overview of the field will be provided and complemented by recent examples where low-frequency vibrational motions are being used to understand, and drive, bulk material function.
