1.3.2.3 Dispersion Forces The weakest van der Waals forces occur between non-polar entities, and are termed dispersion or London forces. They arise because such species have temporary fluctuating dipoles such that at any instant the centre of gravity of the electrons does not coincide with the nu...
London dispersionmolecular switchessteric interactionsLarge substituents are commonly seen as entirely repulsive through steric hindrance. Such groups have additional attractive effects arising from weak London dispersion forces between the neutral atoms. Steric interactions are recognized to have a strong ...
n [fr. Fritz London. (1930) Identifies weak intermolecular forces based on transient dipole interactions. One of van der Waals forces, also called dispersion forces, but distinct from dipole-dipole forces. These forces arise from momentary fluctuations in the electron charge cloud density in a ...
Also known as London forces, dispersion interactions occur between any adjacent pair of atoms or molecules when they are present in sufficiently close proximity. These interactions account for the attractive forces between nonionic and nonpolar organic molecules, such as paraffin and many pharmaceuti...
These forces are called dispersion forces or London forces. Molecules with permanent electric dipoles, such as HCl,NH3, and H2O, experience dipole-dipole forces. These forces are caused by interactions between the polar molecules’ oppositely charged ends. The negatively charged end of one molecule ...
London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, or loosely van der Waals forces) are a type of force acting between atoms and molecules.[1] They are part of the van der Waals forces. The LDF is named after the ...
London dispersion forces are the weakest component of Van der Waals interactions. They arise from attractions between instantaneously induced dipoles on neighbouring atoms. Their relative weakness, in particular for light atoms, such as hydrogen, has led to their importance being largely ignored in disc...
