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.
The intermolecular forces of attraction considered here are: Van der Waals' forces; permanent dipole-permanent dipole interactions; hydrogen bonding; Van der Waals' forces. Van der Waals' forces are forces of attraction which exist between all atoms and molecules. Van der Waals' forces are much weaker than all other types of bonding. They are only significant in atoms and molecules which have no other types of intermolecular forces of attraction, for example, discrete non-polar molecules and the Group 0 elements.
