    • The interactions between the laser-induced polarizabilities and the field place the molecular system in rotational wave packets that are localized in angle space and denote important rotational excitations
    • The interactions between the laser-induced polarizabilities and the field place the molecular system in rotational wave packets that are localized in angle space and denote important rotational excitations 2122. As noted in Ref. 22, these laser-induced excitations are more strongly dependent on the electronic Rabi frequencies than on the intrinsic rotational time. In the present case, the rotational time of (Formula presented) exceeds by far the pulse width. Yet, due to the high field intensity, some alignment of the molecule and its ionic product is expected to arise during the laser pulse action, through these electronically mediated rotational excitations. Here, this alignment is considered to be perfect, i.e., the rotational wave packets are assumed to be singularly localized in angle space. This is certainly an oversimplification.

    • This is about the zeroth-order position of the (Formula presented) two-photon dissociation channel; however, this type of assignment may no longer be meaningful at this intensity, due to strong resonance interaction and residual nonadiabatic transitions between resonances
