• animate a diatomic molecule in two or three dimensions displaying, either separately or simultaneously, translation, rotation, and vibration motions 
• display a molecular-time clock
• display a bar graph of the energy distribution among translation, rotation, and vibration
• allow complete control over initial conditions
• allow the user to interactively accelerate or slow the molecular motion

The atoms are represented by circles or spheres having radii proportional to the covalent radii of the atoms, while the interatomic forces are modeled using a Morse potential energy function which allows realistic vibration and dissociation.

The screen image below illustrates the three-dimensional animation of hydrogen bromide.
