Currently, several X-ray free electron laser (XFEL) facilities are being constructed in the world, and some of them are already in use, e.g., in Japan and US. They are expected to be powerful tool in analyzing protein structures, transient intermediates in chemical reactions and so on. Using XFEL, we can create novel double core-hole (DCH) vacancy state, two inner-shell electron ionized state, in molecule, which has been difficult to create and detect in conventional experiment. Although the DCH states have been detected for several molecules, their basic properties are not understood well. I have performed theoretical studies on molecular DCH states, e.g., relation between ionization energies of DCH states and their molecular environment, satellite states in photoelectron spectra of DCH formation, analysis of Auger decay of DCH states.
