Abstract

The 71g Rydberg state of Na2 correlating with the separated atom limit Na(3s) + Na(5p) has been observed using high-resolution cw optical-optical double resonance spectroscopy. A total of 104 identified rovibrational levels in the range v = 0-12 and 11 ≤ J ≤ 44 have been assigned to the 71g state. Dunham coefficients were determined, and the Rydberg-Klein-Rees potential curve in the range of R = 2.99-4.66 ̊ was derived for the 71g state using the observed quantum levels. The important molecular properties are the potential minimum Te = 36 633.00(23) cm -1 at Re = 3.6313(29) ̊, ωe = 115.75(13) cm-1, and Be = 0.111 22(17) cm-1. A detailed discussion of this investigation of the 71g state is provided.
