結晶中における分子のペダル運動

抄録

This review introduces pedal motion of molecules in crystals, where a pair of benzene rings in a molecule move like the pedals of a bicycle. The pedal motion brings about conformational interconversions, which result in disordered crystal structures. This type of molecular motion takes place in a wide range of compounds. This review describes how to investigate molecular motions using X-ray diffraction analysis, especially focusing on disorder analysis as a function of temperature.
