Absolute absorption cross sections for the lowest excited states (4 2Γ) of Xe2Cl and Kr2F have been measured at discrete wavelengths in the visible and ultraviolet (Xe2Cl: 325 ≤ λ ≤ 495 nm; Kr2F: 248 ≤ λ ≤ 570 nm). The wavelengths observed for the 9 2Γ ← 4 2Γ band peak in each spectrum confirm the predictions of theory. However, the spectral profile and magnitude of the Xe2Cl and Kr2F absorption cross sections are considerably different from those predicted theoretically for the corresponding rare gas dimer ions, Xe+2 and Kr+2.
