Triplet states of Na-2 and Li-2 by perturbation facilitated optical-optical double resonance spectroscopy

We present a review of Li-2 and Na-2 triplet states. We summarize experimen tal results by perturbation facilitated optical-optical double resonance (P FOODR) and all-optical triple resonance techniques as well as other laser s pectroscopic results. We review the PFOODR singlet similar to triplet mixed window levels, the hyperfine structure of the triplet states, their predis sociation, bound-free transitions in the triplet manifold, and collisional energy transfer within triplet states and between singlet and triplet state s.
