Nuclear magnetic resonance (NMR) is the premier technique for characterization of molecular structure and dynamics. Solid-state NMR (SSNMR) is widely used for the study of organic, inorganic, and biological materials, and aids researchers in understanding the nature of the compounds they have synthesized or materials they have produced, as well as providing a means for rationally designing new synthetic and preparative methods. Most SSNMR experiments related to chemical synthesis and materials science are commonly conducted over a relatively narrow temperature range (e.g., -150 C to 250 C). Conversely, low-temperature (LT) experiments down to 20 K (i.e., -253 C) are rarely conducted by chemists, due to the expenses and technical difficulties associated with the design and operation of LT magic-angle spinning (MAS) probes.

核磁共振是表征分子结构和动力学的首要技术。固体核磁共振被广泛应用于有机、无机和生物材料的研究，帮助研究人员了解他们合成的化合物或产生的材料的性质，并为合理设计新的合成和制备方法提供手段。大多数与化学合成和材料科学有关的SS核磁共振实验通常在相对较窄的温度范围内进行(例如，-150摄氏度至250摄氏度)。相反，由于设计和操作低温魔角旋转(MAS)探头的费用和技术困难，化学家很少进行低至20K(即-253摄氏度)的低温(LT)实验。
