Collision‖ Stroboscopic record of a collision between four diatomic molecules, a tetra-atomic molecule and an atom This is the stroboscopic record of a collision between four diatomic molecules, a tetra-atomi molecule and an atom the vibrations and rotations of the molecules before and after collision are seen in the peculiar intertwining paths executed by the atoms in the molecule. This is a classica picture of the collision showing chaos in the very complicated and sensitive dependence on exactly where the atoms are as they begin to collide. The collision proceeded from top to bottom the molecules entering the scene from the top and upper left, and after colliding in the middle, exit on the bottom and lower right, although two diatomic molecules started within the sceneCollision II Stroboscopic record of a collision between four diatomic molecules, a tetra-atomic molecule, and an atom.
