The Standard Model of particle physics is one of the most successful models of the universe, yet it is known to be incomplete. Substantial efforts on the theoretical front introduce new physics through extensions of the Standard Model. Advances in quantum control of molecules have resulted in some of the most stringent constraints on physics beyond the Standard Model [1,2]. Extensive molecular spectroscopy of ²³²ThF⁺ [3-5] has been motivated by the immense sensitivity of the molecule to the electron’s electric dipole moment and promised long coherence time in the molecular science state [4-7]. Building upon this work, we propose the measurement of the Schiff moment, a physical quantity that could hint at new physics, on the isotopologue ²²⁷ThF⁺. Herein, we discuss the complications of working with radioactive ²²⁷Th and provide a teaser of the status of the experiment.
