Solid-State Nuclear Magnetic Resonance (NMR) Spectrometer

Nuclear magnetic resonance (NMR) spectroscopy is achieved by exciting an atom's quantum spin state and examining the energy released during its relaxation. This provides information on the identity and environment of the molecules present. Additionally, the longer relaxation time scale associated with NMR allows for various molecular dynamics and kinetics to be studied. Due to atomic spin state interactions with molecular electron orbitals, normal solid-state radio frequency absorbances tend to be broad and unanalyzable. Using magic angle spinning solid-state NMR spectroscopy, artificial "molecular tumbling" can be introduced, improving the resolution otherwise associated with solid-state NMR and creating analyzable spectra.
