Spectra of highly excited molecules are often difficult to untangle. Such spectra are of interest because of the information they may provide concerning intramolecular vibrational redistribution (IVR). A technique to untangle them is presented here. Hierarchical trees are generated from molecular spectra by following the manner in which spectra change with increasing resolution. Careful examination of such trees, including statistical analyses, can yield important information about spectra. This includes, for example, the time scales for various types of intramolecular energy transfer implied by a spectrum. The analysis of a double resonance spectrum of benzene is presented.
