Dynamical NMR spectroscopy provides unique mechanistic understanding of the transport and relaxation processes in glass-forming liquids over timescales typically ranging from ~10-9 s to ~102 s, and thus has been used extensively in the past to study the dynamical behavior of polymeric and organic glass-forming liquids. However, reports in the literature of similar studies on inorganic glass-forming liquids have remained somewhat limited due to the experimental challenges. In this contribution we present a review of the high-temperature NMR spectroscopic studies of atomic and molecular dynamics in a wide variety of inorganic glass-forming liquids including oxides, halides and chalcogenides as well as select ionic liquids and molten salts. The significance of these dynamical processes in understanding the nature of the liquid-to-glass transition and their connection with the macroscopic transport properties of these liquids are discussed.

用核磁共振波谱法测定无机玻璃形成液体的动力学

动态核磁共振光谱提供了对玻璃形成液体中传输和弛豫过程的独特机械理解,时间尺度通常为 ~10-9 s 到 ~102 s,因此在过去被广泛用于研究聚合物和有机玻璃形成液体。然而,由于实验挑战,关于无机玻璃形成液体的类似研究的文献报道仍然有限。在这篇文章中,我们回顾了对各种无机玻璃形成液体(包括氧化物、卤化物和硫属元素化物)以及选择的离子液体和熔盐中原子和分子动力学的高温 NMR 光谱研究。
