Motivated by the search for new physics using large quantities of trapped polar molecules, we have investigated the optical and radio-frequency spectroscopy of BaF molecules trapped in neon ice at 5K.
I will discuss our contributions to this area at the intersection of physical chemistry and experimental high-energy physics, describing our work on survey and high-resolution laser spectroscopy, optical pumping of BaF electron spins, and precision measurement of hyperfine resonances.
I will provide a summary of the future challenges involved in developing these platforms into practical experiments, which could lead to improved searches for the electron electric dipole moment.
