Laser Spectroscopy and Predissociation of Molecules
Predissociation is a process in which a molecule in an excited state e can be transferred into a dissociative state of the same energy. Figure 1 shows a typical situation for a diatomic molecule, e is a rovibronic state labeled by its vibrational and rotational quantum numbers v and J. It belongs to an electronic excited state E. From E, the molecule can either go back to a lower electronic state G by spontaneous emission of radiation or be transferred to the dissociative state D by an internal or an externally induced coupling.
To a large extent predissociation is therefore comparable to an atomic autoionization process and many conclusions that will be given in this paper can be applied to autoionization.
