“…This means that the direct observation of the intensity modulation of the emitted radiation can be used to obtain real-time information about nuclear vibrations in molecules. The wavelet analysis, already successfully employed to investigate the electron dynamics in atoms and molecules [12,[14][15][16][17][18], is thus also a powerful tool to gain information on the nuclear motion in molecules.…”

The dynamics of hydrogen-like molecules is investigated beyond the usual fixed nuclei approximation. The nuclear motion introduces in the familiar spectrum of emitted radiation additional regular lines whose separation is essentially given by the vibrational frequency of nuclear motion. A wavelet analysis of the emitted spectrum shows that the intensity of the harmonic lines is modulated with the same period of the nuclear motion; this suggests the possibility of the real-time control of the nuclear dynamics.

“…The molecule is supposed to have only one active electron and, because of the large difference between the masses of the nuclei and of the electron, the study of the system is simplified by the ansatz that the motion of the nuclei can be safely described by the classical Newton laws [6,7,8]. Finally we analyze only one-dimensional model systems to avoid lengthy numerical calculations.…”

We study the behaviour of a homonuclear molecule driven by an intense laser field. Newton's laws are used to describe the dynamics of nuclei while the quantal approach is reserved to the study of the electron. It is observed that the nuclei can oscillate or dissociate according to the degree of ionization of the molecule. In case of low ionization rate it is shown that great amount of information can be obtained by using the simplified approaches of fixed nuclei and of two-state approximation. Under suitable conditions the electron wave function spends a long time localized around one nucleus. The harmonic generation of the molecule is studied and seen to contain even harmonics.
