Molecular photoionization as a probe of vibrational–rotational–electronic correlations

Abstract

We determine the rotationally state‐resolved 2σ_u^(−1) photoionization of N_2 into alternative vibrational channels as a function of energy over a 200 eV range. Experiment and theory reveal that Cooper minima highlight the coupling between electronic, vibrational, and rotational degrees of freedom over this very wide range
