Pressure-Induced Behavior of Atoms and Molecules

Received Date: 20 July 2020

In recent years, a large number of new materials and novel phenomena have been discovered and predicted at high-pressure. In this paper, the effects of high pressure on atomic orbital energy and chemical bonds are discussed based on basic chemical principles. Under high pressure, the energy of atomic orbitals changes, which causes the rearrangement of the electrons, and affects the chemical properties of the elements. In the case of molecules, molecular crystals undergo phase transitions under high pressure, unsaturated compounds undergo self-polymerization, and saturated compounds may be metallized.
