Decay and dissociation dynamics of core-excited polyatomic molecules

Abstract

The importance of nuclear motion in the decay and dissociation processes of the core-excited molecules is emphasized by reviewing some case studies. Discussed examples include fast dissociation of P2 p core-excited PH 3 followed by the electron emission from the core-excited fragment PH 2, molecular deformation of the B1 s core-excited state of BF 3 and its effect to the resonant Auger spectra, and symmetry breaking of the highly symmetric molecule SF 6 caused by F1 s core excitation.
