Attosecond time delays in photoionization in molecules are an extremely sensitive probe of electronic correlation effects and nuclear dynamics. The goal of this project is the characterization of the attosecond time delays in small molecules (such as H2O and CH4) in the molecular frame. The orientation of the molecule at the photoionization instant will be determined by measuring in coincidence the photoion and the photoelectron generated by the combination of an attosecond pulse train and a synchronized infrared field. Information on the anisotropic molecular potential will be gained by comparing the emission delays for different spatial directions. (G. Sansone)
