The rotationally resolved absorption spectrum of the 6Li20Ne and 7Li20Ne 3s2Σ+ ← 2p2 II transition has been observed. For each isotope, thirteen vibrational transitions from four vibrational levels (v\"=0, 1, 2, and 3) of the lower 2p2 II to six (v’=0, 1, 2, 3, 4, and 5) of the upper 3s*Σ+ electronic state have been rotationally analyzed. Adiabatic potentials and dissociation energies for both states have been obtained through an inverse perturbation analysis. For the 2p2II state, a well depth of 212(5) cm-1 and an equilibrium separation of 4.36(2) a,, have been obtained. Analysis of the 3s2Σ+ electronic state has revealed a barrier greater than 60 cm'-1 above the atomic Li 3s asymptote and a well of 570(7) cm-1 located at 4.11(1) ao below the asymptote. An anomalously large spin-orbit constant of A =2.77(3) cm'1 was determined for the 2p2II (v\" =0) state while no splitting is observed for transitions out of any 2p2II level with v\" >0.
