摘要

The Na₂ (σ_g3s)(4dδ_g) 2³Δ_g state has been studied by CW sub-Doppler perturbation-facilitated optical-optical double resonance (PFOODR) spectroscopy. Twenty-three vibrational levels have been observed with resolved fine-hyperfine structure. The fine-hyperfine coupling scheme of the 2³Δ_g state is exactly the same as the Na₂ (σ_g3s)(3dδ_g) 1³Δ_g: case b_βs coupling with Fermi contact constant b = 221.7 MHz. Absolute vibrational numbering of the 2³Δ_g state has been determined from the PFOODR fluorescence to the b³Π_u state. The Dunham coefficients were then derived and the corresponding RKR potential curve was determined.
