Coherent control theory has been applied to steer molecular vibrational dynamics so far disregarding the rotational degree of freedom. In this paper the complete rovibrational molecular Hamiltonian is considered, especially its effect on the controllability. It is shown that suitably shaped pulses can overcome the difficulties arising from the reorientational motion of the molecule achieving again a high degree of laser control.
