Pure long-range ion-pair Cs2 molecules
We performed absorption measurements in dense cesium vapor, around the Cs second principal series lines (6s+7p). Three satellite bands peaking at 454.3, 459.1 and 471.6 nm are found. New ab initio Cs2 potential curves calculated with the inclusion of the spin-orbit interaction are used for the identification and simulation of observed satellite bands. The 454.3 and 459.1 nm satellite bands stem from avoided crossings of long-range ion-pair potential curves with long-range covalent potential curves associated with various asymptotes. Semiclassical spectral simulations of these ion-pair satellite bands show satisfactory agreement with measured spectra.
