The EDMcubed collaboration is working towards a measurement of the electric dipole moment of the electron (eEDM) using barium-monofluoride (BaF) embedded in an argon solid. The large numbers of embedded BaF in this measurement scheme  gives the potential for a very precise eEDM measurement. In this work, we present precise relativistic electronic structure calculations (all-electron, with an extrapolation to a complete basis set) of the BaF-Ar tri-atomic system, for a wide range of BaF-Ar separations and angles. The resulting BaF-Ar potential can be parameterized and used to model a BaF molecule embedded into an Ar solid to determine the structure of the local environment around the BaF molecule.
