The electric dipole moment of polar molecules and their rich internal structure makes them excellent candidates for applications in precision measurements, controlled ultracold chemistry, and quantum simulations. Many applications require that the molecular sample is cooled to limit the number of occupied quantum states and trapped.
Aluminum monochloride (AlCl) is a promising candidate for realizing such cold molecule experiments. Its high photon scattering rate and highly diagonal Franck-Condon factors (~99.88%) makes AlCl an excellent candidate to apply laser cooling techniques. Here we report on our progress towards slowing and cooling a cryogenic buffer-gas beam of AlCl. Moreover, we report the first measurement of the electric dipole moment of AlCl, which feeds directly into astrophysical models.
