摘要
A new high-pressure phase transition of pyridine at 5.0 GPa was found using Raman and IR spectroscopy. Application of pressure over 20 GPa induced irreversible polymerization of pyridine, and a yellow-brownish solid material was recovered at ambient condition. The X-ray diffraction pattern revealed that the recovered solid material contained a crystalline phase in contrast to amorphization of other aromatic compounds in a similar pressure region.
