AB - An excellent candidate molecule for the measurement of the electron's electric dipole moment (eEDM) is thorium monofluoride ( ThF + ) because the eEDM–sensitive state,  3 Δ 1, is the electronic ground state, and thus is immune to decoherence from spontaneous decay. We perform spectroscopy on  X 3 Δ 1  to extract three spectroscopic constants crucial to the eEDM experiment: the hyperfine coupling constant, the molecular frame electric dipole moment, and the magnetic  g  factor. To understand the impact of thermal blackbody radiation on the vibrational ground state, we study the lifetime of the first excited vibrational manifold of  X 3 Δ 1 . We perform ab initio calculations, compare them to our results, and discuss prospects for using  ThF +  in an eEDM experiment at JILA.
