dispersion interaction的意思|示意

'

Dispersion interaction is an important component of the intermolecular forces that drive chemical binding among molecules. It is a long-range attractive force that is caused by the electric dipole-induced dipole interactions between molecules.

The force is mainly caused by the fluctuating electric dipoles in the molecules, which become induced dipoles in nearby molecules. It results from the uneven distribution of electrons in the electrons of a molecule and is significantly weaker than the normal covalent or ionic bonds that make up molecules. Dispersion forces are particularly important in the interactions between non-polar molecules, since they are the only type of force that exists between them. These forces can be used to explain the forces of attraction between two non-polar molecules and the shape of molecules.

Dispersion forces are also responsible for the formation of bubbles in solutions and solids, as the molecules interact with each other at an atomic level. As a result, the stability of solutions and solids is mainly determined by the strength of these forces, which can be affected by temperature, pressure, and the presence of other substances. Dispersion forces are also important in the interactions between atoms, as they can influence the properties of a material.

Overall, dispersion interaction is an important component of both intramolecular and intermolecular forces that are responsible for the physical and chemical properties of molecules and materials. It is important to understand the role of dispersion interaction in order to accurately predict chemical behavior and develop strategies that maximize the value of a given substance.
