Title: Precise Access to the Molecular-Frame Complex Recombination Dipole through High-Harmonic Spectroscopy

Abstract

In this paper, we report on spectral intensity and group delay measurements of the highest-occupied molecular-orbital (HOMO) recombination dipole moment of $${\mathrm{N}}_{2}$$ in the molecular-frame using high harmonic spectroscopy. We take advantage of the long-wavelength $$1.3\text{ }\text{ }{\mu}\mathrm{m}$$ driving laser to isolate the HOMO in the near threshold region, 19–67 eV. Finally, the precision of our group delay measurements reveals previously unseen angle-resolved spectral features associated with autoionizing resonances, and allows quantitative comparison with cutting-edge correlated 8-channel photoionization dipole moment calculations.
