Solid State NMR Spectroscopy
Nuclear Magnetic Resonance (NMR) are approaches that utilized in the observation of magnetic nuclei within a strong and constant magnetic field. The nuclei are usually perturbed by a weaker oscillating magnetic field, and responds by producing an electromagnetic signal with a certain frequency characteristic. These types of experiments are preferred because of the relative ease in preparing samples, and an effective ability to quantify metabolite levels. With these experiments, users can obtain very rich and comprehensive structural information. The NMR spectroscopy is essential in identifying the structure, behavior, and concentration of the substances. When substances or reactions are investigated using NMR experiments, there is much better insight into the mechanism of the reactions. Solid-state NMR spectroscopy are usually characterized by the presence of interactions that are dependent on directions. In this regard, these type of NMR experiments require special hardware due to the high-power angular magnetic fields as well as the radio frequency irradiation (Zujovic, et al., 2006; Zujovica, Wheelwright, Kilmartin, Hanna, & Cooney, 2018).
