We present combined theoretical and experimental work investigating the angle-resolved phases of the photoionization process driven by a two-color field consisting of an attosecond pulse train and an infrared pulse in an ensemble of randomly oriented molecules. We derive a general form for the two-color photoelectron (and time-delay) angular distribution valid also in the case of chiral molecules and when relative polarizations of the photons contributing to the attosecond photoelectron interferometer differ. We show a comparison between the experimental data and theoretical predictions in an ensemble of methane and deuteromethane molecules, discussing the effect of nuclear dynamics on the photoionization phases.

- In extreme ultraviolet spectroscopy, molecules can undergo rapid nuclear motion due to the absorption of a photon, which is studied using advanced techniques like attosecond photoelectron interferometry.
- By employing this technique, researchers can examine how nuclear movements of different isotopes, like methane and deuteromethane, impact the characteristics of photoelectron spectra.
- The findings reveal that nuclear dynamics significantly influence the electronic wave packet emitted during photoionization, with effects observable within just a few femtoseconds.
