The [17.8]0(+)-X(1)Σ(+) (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 X(1)Σ(+)(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 (3)Π state. A comparison with the numerous published theoretical predictions is made.
金单氟化物的 [17.8]0(+)-X(1)Σ(+) (0,0) 带已在 40MHz 的分辨率下被记录下来，无论是在无场还是存在静态电场和磁场的情况下。观察到的斯塔克位移被分析以确定 [17.8]0(+)(v = 0) 和 X(1)Σ(+)(v = 0) 态的永久电偶极矩 μel 分别为 2.03 ± 0.05 D 和 4.13 ± 0.02 D。对于 [17.8]0(+)(v = 0) 态观察到的小磁场调谐归因于与 [17.7]1 态的旋转和磁场混合，并使用 (3)Π 态的有效哈密顿量成功地进行了建模。与众多已发表的理论预测进行了比较。
