Abstract We reported the results of the hyperfine structure (HFS) of the 23II1g state in Na2. The relative ultraviolet and visible fluorescence spectra of molecular sodium were measured by means of Doppler-free two-photon spectroscopy technique. The HFS of the 23II1g(v = 78, J = 37, Ω = 1) level was first observed and its HFS constant was measured to be C = -4.92±0.26MHz. The intermediate enchancing and upper energy levels were labled by the experimental and theoretical methods.
