The relative ultraviolet and visible fluorescence spectra of molecular sodium were measured by means of a Doppler-free two-photon spectroscopy technique. The HFS of the 23Hg(v = 78, J = 37,Ω = 1) level was first observed and its HFS constant was measured to be C = -4.92 ± 0.26 MHz. The intermediate enhancing and upper energy levels were labelled by the experimental and theoretical methods.展开更多
