要旨:
As in NMR of liquid samples, solid state NMR probes the magnetic interactions of atomic nuclei. These interactions yield detailed information about the local structure and dynamics of the sample, including the bonding types and geometry, the site-site connectivity patterns, and the spatial characteristics and time-scales of atomic and molecular motions. All kinds of solids can be studied with NMR, including single crystals and powders, disordered materials such as glass and rubber, and metals and superconductors. Spectral resolution, although not as high as in liquid-state NMR, is extraordinary (parts per million or better) but sensitivity is not. Sample volumes of order 50 microliters are typical.
