Abstract
An ab initio non-perturbative time dependent method to describe ionization of molecular systems by ultrashort (femtosecond) laser pulses has been developed. The method allows one to describe competing processes such as non dissociative ionization, dissociative ionization and dissociation into neutrals, including the possibility of autoionization. In this work we assess the validity of the method by applying it to different physical situations and by comparing with results previously obtained within stationary perturbation theory. In particular, it is shown that inclusion of the nuclear motion is essential to describe H2 resonance enhanced multiphoton ionization and interferences mediated by H2 autoionizing states.
