在钙离子{MATHROM{F}}{2}$中不同位置的离子的光谱中观察到塞曼效应。除了Kirton和McLaughlan所报道的ESR与光谱之间的一个关联之外，所有的关联都得到了检验和确认，并确定了上态的$g$值。我们已经消除了菱形光谱解释中的模糊性，并且我们以90%的信心证明了立方晶位中的${mathrm{Yb}^{3+}$的上态分裂大于18.3${mathrm{cm}}^{ensureath{-}1}$。
The Zeeman effect has been observed in the optical spectra of ${mathrm{Yb}}^{3+}$ ions in different sites in Ca${mathrm{F}}_{2}$. All but one of the correlations between ESR and optical spectra, reported by Kirton and McLaughlan, have been checked and confirmed, and the upper-state $g$ values have been determined. Ambiguity in the interpretation of the rhombic spectra has been eliminated, and we have shown with 90% confidence that the upper-state splitting of ${mathrm{Yb}}^{3+}$ in cubic sites is greater than 18.3 ${mathrm{cm}}^{ensuremath{-}1}$.
