The molecular ion ThF+ is the species to be used in the next generation of search for the electron’s Electric Dipole Moment (eEDM) at JILA. The measurement requires creating molecular ions in the eEDM sensitive state, the rovibronic ground state 3 Δ 1, v+= 0, J+= 1. Survey spectroscopy of neutral ThF is required to identify an appropriate intermediate state for a Resonance Enhanced Multi-Photon Ionization (REMPI) scheme that will create ions in the required state. We perform broadband survey spectroscopy (from 13,000 to 44,000 cm− 1) of ThF using both Laser Induced Fluorescence (LIF) and 1+ 1′ REMPI spectroscopy. We observe and assign 345 previously unreported vibronic bands of ThF. We demonstrate 30% efficiency in the production of ThF+ ions in the eEDM sensitive state using the Ω= 3/2 [32.85] intermediate state. In addition, we propose a method to increase the aforementioned efficiency to∼ 100% by using vibrational autoionization via core-nonpenetrating Rydberg states, and discuss theoretical and experimental challenges. Finally, we also report 83 vibronic bands of an impurity species, ThO.
