摘要：

The Na2 (σg3s)(4dδg) 23Δg 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 23Δg state is exactly the same as the Na2 (σg3s)(3dδg) 13Δg: case bβs coupling with Fermi contact constant b = 221.7 MHz. Absolute vibrational numbering of the 23Δg state has been determined from the PFOODR fluorescence to the b3Πu state. The Dunham coefficients were then derived and the corresponding RKR potential curve was determined. © 1991.
