Abstract
The splitting of Î-doubling in the 51Î g Rydberg state of Na2, which dissociates to Na(3s) + Na(4d), has been measured using the high-resolution cw optical-optical double resonance technique. The observed data are in the range of 0 ⩽ v ⩽ 22 and 11 ⩽ J ⩽ 83 with Î-doubling revealed. A set of Dunham coefficients with Î-doubling constants has been obtained from the experimental results. The splitting of Î-doubling increases quadratically with the rotational quantum number J and weakly depends on the vibrational quantum number v. These splitting constants are much larger than those in the Na2B1Î u state, which dissociates to Na(3s) + Na(3p). This indicates that the splitting of Î-doubling in the 51Î g state is affected by both the perturbations by adjacent Σ states and the L-uncoupling.
