A number of interpreted spectra are available for interactive JSmol (Jmol/JSpecView) display

JSmol (HTML5 only)
The spectra are "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.
You can use the Jmol menu or alternatively select an
