N,N-diethylmethylamine (diethylmethylamine, DEMA) is a tertiary amine with the formula C 5 H 13 N. N,N-Diethylmethylamine is a clear, colorless to pale yellow liquid at room temperature, and is used in various industrial and scientific applications including water desalination as well as analytical and organic chemistry.. Diethylmethylamine is an acute oral and inhalation toxin although limits. Solid-state NMR (ssNMR) spectroscopy is a special type of nuclear magnetic resonance (NMR) spectroscopy, characterized by the presence of anisotropic (directionally dependent) interactions. Compared to the more common solution NMR spectroscopy, ssNMR usually requires additional hardware for high-power radio-frequency irradiation and magic-angle spinning. Solid‐state nuclear magnetic resonance (NMR) spectroscopy is a versatile analytical tool for the characterization of various types of materials. It is frequently applied to investigate the structure, dynamics, and flexibility of metal–organic framework (MOF) by: 1.

Nuclear magnetic resonance (NMR) is a spec-troscopic technique that detects the energy ab-sorbed by changes in the nuclear spin state. The application of NMR spectroscopy to the study of proteins and nucleic acids has provided unique in-formation on the dynamics and chemical kinetics of these systems.
