The [17.8]0+-X1Σ+ (0,0) band of gold monofluoride, AuF, has been recorded at a resolution of 40 MHz both field free and in the presence of a static electric and magnetic field. The observed Stark shifts were analyzed to determine the permanent electric dipole moment, μel, of 2.03 ± 0.05 D and 4.13 ± 0.02 D, for the [17.8]0+(v = 0) and X1Σ+(v = 0) states, respectively. The small magnetic tuning observed for the [17.8]0+(v = 0) state is attributed to rotational and magnetic field mixing with the [17.7]1 state and has been successfully modeled using an effective Hamiltonian for the 3Π state. A comparison with the numerous published theoretical predictions is made.
