シアノ化合物の相転移と固相重合反応

抄録

Cyanides tend to form linear chains of molecules in solid, which are tightly bonded by strong intermolecular interactions due to highly polar cyano group; they are hydrogen bonding and dipole-dipole interactions. Hydrogen cyanide and acetonitrile are prototypes of cyanides, showing chracteristic structural phase transitions under pressure with rearrangement of linearly aligned molecules. Vibrational spectral study of the phase transition and chemical reaction in cyanides are reviewed.
