Abstract
An automatic quantum-based method to find and extract the relevant localizations of a dynamical system is presented and applied to three-dimensional H+ 3 vibrational calculations. The method exploits the relationship between expressions in the time domain and the energy domain, extracting from groups of eigenstates the localization information related to short term structures in the dynamics. Several localizations are found and extracted. Special emphasis is placed on bending and dissociating motions.
