Demo Chemical Bonding Curves


This self-standing demonstration experiment shows the shapes of curves for potential energy and force for seven expressions commonly used in chemical bonding. They include Hooke's law, Lennard-Jones 6-12, ionic (in two forms), Born-Mayer, Mie, Morse, Buckingham. The potential is in a dimensionless form of -U/Uo versus distance as r/ro, where Uo is the potential at equilibrium distance ro. Force is dimensionless by its maximum value Fmax.


A control panel allows you to change the potential expression and vary the key parameters. A ClipIt button allows you to take a snapshot of the curves at a given set of parameters in order to compare to curves at other parameter settings.
