Both applets have callback routines available that can be accessed using JavaScript. For JSpecView, the X,Y coordinates of the point clicked are returned. For Jmol, the ID of the atom clicked is determined. These are then compared to information stored in a small JavaScript array.

The effect is that the spectra appear "hot-linked" to the molecular graphic display such that selecting a peak in the IR spectrum will cause a vibrational mode animation to be loaded, or selecting a peak in the NMR spectra will cause the appropriate H or C atoms to be highlighted.
