Single Ion Transitions in Ionic Diatomic Molecules

摘要

The conventional model for freehyphen;ion electronic transitions in KCl:Tlplus;and related systems implies comparable transitions in diatomic Mplus;Xminus;for suitable Mplus;, e.g., alkaline earths. Correlations are facilitated by comparing optical bands of Mplus;Xminus;with term values of the nearest isoelectronic neutral atom. The available data for the diatomic halides CaX, SrX, BaX, SnX, HgX, and PbX provide evidence for single ion transitions.
