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.
A temporary dipole on one molecule (formed by the random motion of. electrons in the molecule) induces a temporary dipole on neighboring molecules. These temporary dipoles experience attraction for each other. London forces exist between all types of molecules. The strength of. London forces depends on the molar mass of the molecule (higher MM â more. electrons â more polarizable â stronger London forces) and, to a lesser extent, on surface area (greater surface areaâ stronger London forces).
