Full article in JCE Internet at http://jchemed.chem.wisc.edu/JCEWWW/Articles/WWW0001/ Matrix algorithms are employed with computer graphics to generate accurately scaled digital animations of the 3N-6(5) normal modes of vibration. Embedded movies display multiple panels that allow each vibrational mode to be observed simultaneously along with the composite superposition of the individual modes. This unique feature allows the viewer to identify contributions of each mode to the dynamics of the complex zero- point motion. The origin of vibrational angular momentum is disclosed in an animated superposition of degenerate vibrational modes.
