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 P 2p core-excited PH3 followed by the electron emission from the core-excited fragment PH2, molecular deformation of the B 1s core-excited state of BF3 and its effect to the resonant Auger spectra, and symmetry breaking of the highly symmetric molecule SF6 caused by F 1s core excitation.
