Symmetry breaking is an important phenomenon connected to the excitation of core electrons in molecules. The fundamental question of whether inner-shell electronic-state orbitals are delocalized, and what the underlying mechanism for breaking the symmetry of a molecule upon dissociation are the subject of much debate, especially for the case of diatomic molecules. One method for studying molecular fragmentation, which is based upon a symmetry picture, is multicoincidence ion spectroscopy. Here we give a brief presentation of some of the applications of this technique, where symmetry, nuclear motion and the temporal signature are of importance.
