N2 - This paper reports a high-resolution experimental study of the 33Πg and 43Σ+g electronic states of the 85Rb2 dimer. In the experiment, rovibrational levels of the two electronic states were probed using the perturbation facilitated optical-optical double resonance technique by exciting 85Rb2 molecules from thermally populated levels of the ground X1Σ+g state through intermediate levels of the mixed A1Σ+u∼b3Πu electronic states. The resonances of the probe laser were observed by detecting the laser induced fluorescence from the target states to the a3Σ+u triplet ground state. In addition, to confirm the triplet character as well as the vibrational quantum number assignment of the states, for selected resonances the fluorescence to the a3Σ+u state was resolved and bound-free spectra were recorded. From the observed term values for each state potential-energy curves were constructed using the Rydberg-Klein-Rees method.
