Site selective dissociation upon core ionization of ozone
Chem. Phys. Lett. 435, 214 (2007)

Abstract
Ozone is found to exhibit substantial site-selective fragmentation when its fragment ions are collected in coincidence with energy selected electrons. We find a preferential production of the ion pair upon ionization of the terminal (central) oxygen 1s electron. Depending on the hole localization, Auger rates are different towards the various final states of the dication, which would produce the observed different fragmentation pattern. We also observe however an increase production for when the terminal core-hole state is vibrationally excited. This shows the role of the nuclear motion before the Auger decay in the observed site-specific.
