The Na2 2Πg3 state: New observations and hyperfine structure

摘要: Many more Na2 2Πg3 v=0–43, Ω=0,1,2 levels have been observed by sub-Doppler continuous wave perturbation facilitated optical-optical double resonance fluorescence excitation spectroscopy and the hyperfine structure of Ω=0 2 has resolved. New molecular constants for less perturbed v=0–43 obtained with these new previously reported data. The coupling scheme is close to Hund’s case aβ a Fermi contact constant bF=160±5MHz, which smaller than other triplet Rydberg states, bF=200–245MHz.
