High resolution solid state nmr gives information about structure of local sites in solid state samples, and has an advantage over X-ray diffraction method at the point of reflecting difference between nucleuses with near atomic numbers. An outline of CP/MAS nmr, which is a typical high resolution solid state nmr technique, is given here. And, problems of orientational disorder of bridging cyano groups in metal cyanide complexes are introduced as an actual crystal structure study using solid state nmr and diffraction method.
