“…A detailed knowledge of the potential energy curves (PECs) of the alkali metal diatomics is important in the accurate evaluation of the molecular properties and correct understanding of the collision processes. Among alkali metal dimers the Li 2 system plays a special role being a second smallest homonuclear molecule, and due to that, it attracts a lot of interest both from the experimentalists and theoreticians. − The currently available advanced spectroscopic techniques such as OODR (optical–optical double resonance), − AOTR (all optical triple resonance), or CIF (collisionally induced fluorescence) − allow for the precise measurement and the accurate spectroscopic characteristics of electronic states of Li 2 . − …”

A multireference coupled cluster (CC) approach formulated in the (2,0) sector of the Fock space (FS) is applied to study electronic states of the Li2 molecule. The CC model including single (S) and double (D) excitations from the reference configuration is considered. The FS-CCSD(2,0) method is applicable to the description of the double electron attached states, which implies that in the neutral molecule studies the doubly ionized reference should be adopted. The results of this study include potential energy curves (PECs) and selected spectroscopic constants for 34 electronic states correlating to five lowest dissociation limits of Li2. Both the PECs and the computed spectroscopic constants agree very well with the experimental data wherever the latter are available. This indicates that the rigorous ab initio method can be successfully applied to study the energetics and molecular properties of the alkali metal diatomics.

“…Observation of non-resonant two-photon molecular transitions between the X 1 + g and E 1 + g electronic states has not been previously reported. However, energy levels for ro-vibrational states of these electronic potentials can be calculated from Dunham-type coefficients, which have been determined by Kusch and Hessel [11] and Bernheim et al [12,13]. The selection rules, for two-photon electronic transitions are J = 0, ±1, ±2.…”

Coincidence in the two-photon spectra of Li and Li₂at 735 nm

A coincidence between the 22S1/2–32S1/2 two-photon transition in the atomic spectrum of 6Li and the X 1Σ+g→ E 1Σ+g two-photon ro-vibrational series of 7Li2 was observed near 735 nm in a heat pipe oven using a tunable laser and thermionic diode detection scheme. The molecular transition obscures one component of the 6Li atomic transition. Selective detection of the atomic transition was obtained by adding an intensity-modulated laser that drives atoms from the 3S to 16P state. The coincident molecular transition and four nearby molecular lines were identified using previously determined Dunham coefficients.
