Abstract

Dispersed laser induced fluorescence from the rubidium dimer, formed at ~ 260 °C has been recorded at Doppler resolution on an FT spectrometer. The spectra extend observations of the A ¹Σ_u⁺ state to sufficiently low vibrational levels in the A state to allow definitive vibrational assignments to be made for this heavily perturbed electronic state, and to give very plausible ones for the perturbing b ³Π_u state. The two are strongly mixed by spin-orbit coupling.
