记录了冷分子束样品YBF的A(2)PI(1/2)-X(2)Sigma(+)电子跃迁(0，0)带的(O)P(12)分支中塞曼诱导的低J谱线的位移和分裂。用标准的有效哈密顿方法分析了(171)YBF、(172)YBF和(174)YBF同位素的塞曼谱。利用预测和观测到的电子态分布，对A(2)PI(1/2)(v=0)态确定的磁g因子进行了合理化。观测到的A(2)PI(1/2)(v=0)态能级的塞曼调谐出乎意料地大；这是由于与B(2)Sigma(+)态的混合造成的。
The Zeeman-induced shifts and splittings of low-J lines in the (O)P(12) branch of the (0,0) band of the A(2)Pi(1/2)-X(2)Sigma(+) electronic transition of a cold molecular beam sample of ytterbium monofluoride, YbF, have been recorded. The Zeeman spectra for the (171)YbF, (172)YbF, and (174)YbF isotopologues have been analyzed using a standard effective Hamiltonian approach. The magnetic g-factors determined for the A(2)Pi(1/2)(v = 0) state are rationalized using the predicted and observed electronic state distribution. The observed Zeeman tuning of the levels in the A(2)Pi(1/2)(v = 0) state is unexpectedly large; this is caused by mixing with the B(2)Sigma(+) state.
