Abstract
By analyzing the temperature dependence of the absorption spectrum of Cs2 molecules in the visible region of the spectrum we have demonstrated that a group of unusually narrow bands near 7100 Å originate from a very shallow and possibly slightly repulsive part of a ground state potential curve. This may be part of the 3Σ ground‐state potential curve. An analogous set of narrow bands occurs for Rb2 near 6000 Å. The remaining prominent visible absorption bands for Cs2 and Rb2 all originate from molecules near the bottom of the 1Σ ground state.Keywords
