* Intermolecular Forces, non-bonding electrostatic forces between molecules

Intermolecular forces are forces of attraction or repulsion which act between neighboring particles ( atoms, molecules or ions ).

# Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids ).

Intermolecular noncovalent interactions are responsible for protein complexes ( quaternary structure ) where two or more proteins function in a coherent mechanism.

( ii ) Intermolecular theory – molecules can come very close to each other ( less than 50 nm ) at the points of true contact allowing development of

Intermolecular hydrogen bonding is responsible for the high boiling point of water ( 100 ° C ) compared to the other group 16 hydrides that have no hydrogen bonds.

* Intermolecular transesterification can transfer a whole segment from one polypeptide to another, as is seen in the Hedgehog protein autoprocessing.

Intermolecular rearrangements also take place.

The GB tension can also be thought of as the attractive forces between the atoms at the surface and the tension between these atoms is due to the fact that there is a larger interatomic distance between them at the surface compared to the bulk ( i. e. surface tension ).

These interatomic forces in helium are weak to begin with because helium is a noble gas, but the interatomic attractions are reduced even more by the effects of quantum mechanics.

However at greater distances, the effects of the interatomic forces in helium are even weaker.

Because of the very weak interatomic forces in helium, this element would remain a liquid at atmospheric pressure all the way from its liquefaction point down to absolute zero ( an unreachably-low temperature ).

This effect arises from their large zero-point energy and the small interatomic forces, both of which prevent the formation of a solid phase.

The atoms and ions, which are bonded with each other with considerable interatomic forces, are not motionless.

These variations in specificity are the result of interatomic contacts with local residues near the active sites of each subunit.

In adiabatic dynamics, interatomic interactions are represented by single scalar potentials called potential energy surfaces.

The filled d-shells in these elements do not contribute much to the interatomic interactions, which are dominated by the s-electrons through metallic bonds.

The dihedral angle varies only the distance between the first and fourth atoms ; the other interatomic distances are constrained by the chemical bond lengths and bond angles.

These Cooper pairs are substantially larger than the interatomic separation

This is because molecular bonds ( and therefore the interatomic distance ) are not completely fixed ; the bond between the atoms stretches out as the molecule rotates faster ( higher values of the rotational quantum number ).

Dipolar coupling are distance dependent, and so they may be used to calculate interatomic distances in isotopically labeled molecules.

Strained silicon is a layer of silicon in which the silicon atoms are stretched beyond their normal interatomic distance.

spectrum are determined by interatomic bonds.

The peaks in the Patterson function are the interatomic distance vectors weighted by the product of the number of electrons in the atoms concerned.

One can study whether in these systems the analogous process to Hawking radiation still occurs despite the short-scale cutoff represented by the interatomic distance.

John Ernst Worrell Keely ( September 3, 1837 – November 18, 1898 ) was a US inventor from Philadelphia who claimed to have discovered a new motive power which was originally described as " vaporic " or " etheric " force, and later as an unnamed force based on " vibratory sympathy ", by which he produced " interatomic ether " from water and air.

In the context of a BEC, the Feshbach resonance occurs when the energy of a bound state of an interatomic potential is equal to the kinetic energy of a colliding pair of atoms, which have hyperfine structure coupled via Coulomb or exchange interactions.

For local thermodynamic equilibrium, the radiation field does not have to be a black-body field, but the rate of interatomic collisions must vastly exceed the rates of absorption and emission of quanta of light, so that the interatomic collisions entirely dominate the distribution of states of atomic excitation.
