Autoionization of Rydberg states of HfF, prepared using the optical-optical double resonance technique, holds promise to create HfF[superscript +] in a particular Zeeman level of a rovibronic state for an electron electric dipole moment search. We characterize a vibronic band of Rydberg HfF at 54 cm[superscript −1] above the lowest ionization threshold and directly probe the state of the ions formed from this vibronic band by performing laser-induced fluorescence on the ions. The Rydberg HfF molecules show a propensity to decay into only a few ion rotational states of a given parity and are found to preserve their orientation qualitatively upon autoionization. We show empirically that we can create 30% of the total ion yield in a particular |J[superscript +], M[superscript +]〉 state and present a simplified model describing autoionization from a given Rydberg state that assumes no angular dynamics.
