The A2Π-X2Σ+ (0,0) band system of barium monofluoride (BaF) has been recorded using high-resolution laser-induced fluorescence spectroscopy both field-free and in the presence of static magnetic and electric fields. The field-free spectra for the Ba135F, Ba137F, and Ba138F isotopologues were modeled to generate an improved set of spectroscopic constants for the A2Π(υ=0) and X2Σ+(υ=0) states. The observed optical Stark shifts for the Ba138F isotopologue were analyzed to produce the permanent electric dipole moments of 1.50(2) and 1.31(2) D for the A2Π1/2(υ=0) and A2Π3/2 (υ=0) states, respectively. The observed optical Zeeman shifts for the Ba138F isotopologue were analyzed to produce a set of magnetic g factors for the A2Π(υ=0) and X2Σ+(υ=0) states.
