Dipole moment of the YbOH molecule

The YbOH molecule is a sensitive system to use in searches for fundamental symmetry violations. Its molecular-frame permanent and transition dipole moments are of key importance for preparing and interpreting experiments. We calculate these quantities for the lowest bending vibrational modes of the ground electronic state. A high-level coupled cluster method for electronic structure calculations, together with averaging over vibrational states, was employed to obtain accurate values.
