  2. London dispersion force - Wikipedia

    en.wikipedia.org/wiki/London_dispersion_force

    Interaction energy of an argon dimer.The long-range section is due to London dispersion forces. London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds [1] or loosely as van der Waals forces) are a type of intermolecular force acting between atoms and molecules that are normally electrically ...

  3. Intermolecular force - Wikipedia

    en.wikipedia.org/wiki/Intermolecular_force

    The dispersion (London) force is the most important component because all materials are polarizable, whereas Keesom and Debye forces require permanent dipoles. The London interaction is universal and is present in atom-atom interactions as well. For various reasons, London interactions (dispersion) have been considered relevant for interactions ...

  4. Dispersion stabilized molecules - Wikipedia

    en.wikipedia.org/wiki/Dispersion_stabilized...

    Dispersion forces keep the molecule inert even while its core Si-Si bond lengthens. Similarly, the longest known Ge-Ge bond is found in t Bu 3 GeGe t Bu 3 and is also facilitated by dispersion stabilization. [19] Dispersion stabilization has also been invoked for (t BuC) 3 P, a main group analog of a hydrocarbon tetrahedrane. [20]

  5. Molecular solid - Wikipedia

    en.wikipedia.org/wiki/Molecular_solid

    The cohesive forces that bind the molecules together are van der Waals forces, dipole–dipole interactions, quadrupole interactions, π–π interactions, hydrogen bonding, halogen bonding, London dispersion forces, and in some molecular solids, coulombic interactions.

  6. Van der Waals force - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_force

    London dispersion forces are also known as 'dispersion forces', 'London forces', or 'instantaneous dipole–induced dipole forces'. The strength of London dispersion forces is proportional to the polarizability of the molecule, which in turn depends on the total number of electrons and the area over which they are spread.

  7. Dispersive adhesion - Wikipedia

    en.wikipedia.org/wiki/Dispersive_adhesion

    The source of adhesive forces, according to the dispersive adhesion mechanism, is the weak interactions that occur between molecules close together. [2] These interactions include London dispersion forces, Keesom forces, Debye forces and hydrogen bonds. Individually, these attractions are not very strong, but when summed over the bulk of a ...

  8. Lennard-Jones potential - Wikipedia

    en.wikipedia.org/wiki/Lennard-Jones_potential

    The Lennard-Jones potential is a simple model that still manages to describe the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.

  9. Hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_bond

    Examples of hydrogen bond donating (donors) and hydrogen bond accepting groups (acceptors) Cyclic dimer of acetic acid; dashed green lines represent hydrogen bonds Hydrogen bonds arise from a combination of electrostatics (multipole-multipole and multipole-induced multipole interactions), covalency (charge transfer by orbital overlap), and ...
