The (2p + 2p) 2 3Πg and (2s + 3p) 3 3Πg states of 7Li2 have been studied both experimentally and theoretically. Vibrational levels v = 0-41 of the 2 3Πg state and v = 6-10 of the 3 3Πg state have been observed by perturbation facilitated optical-optical double resonance (PFOODR) spectroscopy. Our ab initio calculations show that the 2 3Πg state, although dissociating into 2p + 2p atomic limit, is a Rydberg state and strongly mixed with the (2s + 3p) 3 3Πg and (2s + 3d) 4 3Πg Rydberg states. Our theoretical calculations show good agreement with our experimental results.
