abstract = "The (1,0) [17.9]2.5-X-2 Delta(3/2) band of hafnium monofluoride (HfF) has been recorded using high-resolution laser-induced fluorescence spectroscopy both field-free and in the presence of a static electric field. The field-free spectra of (HfF)-Hf-177, (HfF)-Hf-179, and (HfF)-Hf-180 were modeled to generate a set of fine and hyperfine parameter for the X-2 Delta(3/2)(v = 0) and [17.9]2.5 (v = 1) states. The observed optical Stark shifts for the (HfF)-Hf-180 isotopologue were analyzed to produce the molecular frame electric dipole moments of 1.66(1) D and 0.419(7) D for the X-2 Delta(3/2) and [17.9]2.5 state, respectively. Both the generalized effective core potential and all-electron four component approaches were used in ab initio calculations to predict the properties of ground state HfF including equilibrium distance, dipole moments, quadrupole coupling, and magnetic hyperfine constants.
