Low-temperature Solid-State NMR Probe

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.
