Abstract: Photo-induced molecular processes start with the interaction of the instantaneous electric field of the incident light with the electronic degrees of freedom. This early attosecond electronic motion impacts on the fate of the photo-induced reactions. We report the first observation of attosecond timescale electron dynamics in a series of small and medium-size neutral molecules (N₂, CO₂ and C₂H₄), monitoring time-dependent variations of the parent molecular ion yield in the ionization by an attosecond pulse, and thereby probing the time-dependent dipole induced by a moderately strong near-infrared laser field. This approach can be generalized to other molecular species and may be regarded as a first example of molecular attosecond Stark spectroscopy.
