The electronic and nuclear dynamics of H+2 and H2 in intense laser fields are examined by solving the time-dependent Schrödinger equations for the systems. We clarify the dynamics of bound electrons and the subsequent ionization process in terms of "field-following" adiabatic states. The adiabatic state analysis leads to an electrostatic model in which each atom in a molecule is charged by laser-induced electron transfer and ionization proceeds via the most unsatable atomic site. We apply this model to multi-electron molecules with the help of ab initio molecular orbital calculations; the structure deformations of CO2 cations in an intense field are investigated. The control of electronic and nuclear dynamics is briefly discussed from the viewpoint of the dynamics on adiabatic states.
