London Dispersion Force
London dispersion forces, named after the German-American physicist Fritz London, are weak intermolecular forces that arise from the interactive forces between instantaneous multipoles in molecules without permanent multipole moments. These forces dominate the interaction of non-polar molecules, and also play a less significant role in van der Waals forces than molecules containing permanent dipoles or ionized molecules. London dispersion forces are also known as dispersion forces, London forces, or instantaneous dipole–induced dipole forces. They increase with the molar mass, causing a higher boiling point especially for the halogen group.

Famous quotes containing the words london, dispersion and/or force:
“One of the many to whom, from straightened circumstances, a consequent inability to form the associations they would wish, and a disinclination to mix with the society they could obtain, London is as complete a solitude as the plains of Syria.”
—Charles Dickens (1812–1870)
“The slogan offers a counterweight to the general dispersion of thought by holding it fast to a single, utterly succinct and unforgettable expression, one which usually inspires men to immediate action. It abolishes reflection: the slogan does not argue, it asserts and commands.”
—Johan Huizinga (1872–1945)
“The mass believes that it has the right to impose and to give force of law to notions born in the café.”
—José Ortega Y Gasset (1883–1955)
