The rapid technological progress in ultrashort intense light sources has triggered various research activities in the field of attosecond science, with the ultimate goal to directly measure and control electron and nuclear motion in atoms and molecules. From the theoretical side, ab initio simulations of the electronic and nuclear dynamics in atoms and molecules remain a challenge. In this contribution, we apply the recently developed fully general time-dependent multiconfiguration self-consistent-field (TD-MCSCF) method to the simulation of strong field-induced ionization and dissociation of H₂. By including enough number of configurations, it is shown that the present method is well suited to describe not only the laser-induced ionization but also laser-induced dissociation and vibrational excitation.
