The response of molecular systems to the ultra-intense, femtosecond x-ray radiation from the hard x-ray FEL, the Linac Coherent Light Source (LCLS), was investigated. Sequential multiphoton ionization, frustrated absorption [1] and double core hole production mechanisms [2,3] will be presented. [1] M. Hoener et al., Phys. Rev. Lett. 104, 253002 (2010) [2] L.
