Abstract
We have trapped BaF molecules in neon ice, and used laser-induced fluorescence spectroscopy to map out optical transitions in the trapped molecules. Our measurements show that the neon lattice does not significantly perturb certain optical transitions in the trapped molecules. We used one of these transitions to polarize the electron spins, detect spin flips and measure hyperfine transitions in the trapped molecules, entirely using lasers. This demonstration with heavy polar molecules opens up new opportunities for precision measurements of beyond-standard-model physics.
