Replies: In a sense quadrapole bonds are possible by induced dipole-induced dipole interactions.
The consequent magnetic dipole interactions among the particles cause them to form chain-like clusters, which follow the magnetic field lines and aggregate further to form long filaments.
Interactions with oscillating quadrupoles, etc. are also possible, but are so much weaker than dipole interactions that they can usually be ignored.
This bond may consist of an induced dipole interaction between a hydrophobic matrix and a hydrophobic anchor.
The only thing holding the solid together is the induced dipole-induced dipole interaction, brought about by their mutual polarizability.
The transition dipole moment is useful for determining if transitions are allowed under the electric dipole interaction.
For instance, in iron (Fe) the exchange force is about 1000 times stronger than the dipole interaction.
Debye forces, or dipole-induced dipole interactions, can also play a role in dispersive adhesion.
An association energy of 22-25 kJ/mol is typical of charge-induced dipole interactions, and so there is interest in the use of charged linkers and metals.
Ionic molecules have ion-induced dipole interactions so that salts, strong acids and strong bases tend to dissolve in water.
