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.

“Fashion understands itself; good-breeding and personal superiority of whatever country readily fraternize with those of every other. The chiefs of savage tribes have distinguished themselves in London and Paris, by the purity of their tournure.”
—Ralph Waldo Emerson (18031882)
“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 (18721945)
“Like a kick in the butt, the force of events wakes slumberous talents.”
