Rotationally Resolved Laser Spectroscopy of the 3s2Σ+ ← 2p2II Transition in 6Li20Ne and 7Li20Ne Van Der Waals Molecules

<p>The rotationally resolved absorption spectrum of the ⁶Li²⁰Ne and ⁷Li²⁰Ne 3s²Σ⁺ ← 2p²II 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) a_o 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.</p>
