微波波谱法是一种高灵敏度、高分辨率的研究分子系统内部动力学及超精细结构的方法,能解决许多其他方法难以解决的化学与物理领域具有挑战性的难题。本文综述了微波波谱法研究水分子与有机或生物分子形成分子配合物的内部动力学过程,详细讨论了不同类型的有机或生物分子与水分子形成的分子配合物,介绍了水在分子配合物中作为质子给体和质子受体的动力学,形成分子配合物后水分子和配体分子的隧道运动、结构和构象变化等动力学过程,并讨论了分子配合物中水分子和有机或生物分子的内部运动、相互作用键的强度、对称性影响隧道动力学特性。最后,展望了微波波谱法的发展方向。
Microwave spectroscopy is a highly sensitive, high-resolution method for studying the internal dynamics and ultra-fine structure of molecular systems. It can solve many challenging chemical and physical problems difficult to solve by other methods. In this paper, we review the internal kinetics of the molecular interaction of water molecules with organic or biological molecules by microwave spectroscopy, and discuss the molecular complexes of different types of organic or biological molecules with water molecules in detail. The effects of water on molecular complexes In the kinetics of proton donors and proton acceptors, kinetics of tunnel motions, structure and conformational changes of water molecules and ligand molecules after the formation of molecular complexes, and the interaction between water molecules and organic or biological molecules in molecular complexes The internal dynamics of the molecule, the strength of the interacting bonds, and the symmetry affect the dynamics of the tunnel. Finally, the development trend of microwave spectroscopy is prospected.
