The dynamical behavior of H 2 + in near-infrared, intense laser fields (I > 1013 W/cm2 and λ > 700 nm) was discussed on the basis of the results of accurate electronic and nuclear wave packet propagation obtained by the application of the dual transformation method. Using "field-following" time-dependent adiabatic states defined as the eigenfunctions of the "instantaneous" electronic Hamiltonian including the dipole interaction with laser fields, we clarify the importance of the excited state dynamics in the ionization process. We also discuss the mechanism of ionization of H2 on the basis of the description of the multicofiguration time-dependent Hartree-Fock (MCTDHF) method.
