摘要：

Using resolved fluorescence from a 1Σg + Rydberg state to the A 1Σu+ state of K2, we have observed the lowest vibrational levels (v′≤12) of the A 1Σu+ state. Levels v′ = 21 to 62 (well beyond the previously known v′ = 12 to 18 region) were observed using the polarization optical-optical double resonance technique. Molecular constants and a Rydberg-Klein-Rees (RKR) potential energy curve based on these constants are given. Franck-Condon factors for the K 2 A 1Σu+-X 1Σg+ system based on this new A 1Σu+ potential are also given. © 1990 American Institute of Physics.
