At the death of Armisteads widow in 1861, the Star-Spangled Banner was bequeathed to his daughter, Georgiana Armistead Appleton, who recognized that it held national as well as familial significance. As its owner, she permitted the flag to be publicly exhibited on several occasions.
London Dispersion Forces. The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
London forces are present between all chemical groups, and usually represent the main part of the total interaction force in condensed matter, even though they are generally weaker than ionic bonds and hydrogen bonds.In solution dispersion force are weakend by competition with polarizable solvent molecules; the interactions are very weak between hydrocarbons but are sizeable if heteroatoms are are involved.
