✦ Synopsis

Single-photon transitions of jet-cooled Xe 2 have been recorded using a vacuum ultraviolet laser operating between 82 386-82 587 cm 01 and 83 706-84 006 cm 01 . Molecular ions produced by (1 / 1) resonance enhanced multiphoton ionization and atomic fragment ions resulting from excited state predissociation were mass selected in a linear time-offlight mass spectrometer. Subsequent vibrational analyses have led to molecular constants for two Rydberg states which dissociate to Xe( 1 S 0 ) / Xe*5d[5/2] 0 3 and Xe( 1 S 0 ) / Xe*5d[3/2] 0 1 , respectively. Excited state equilibrium bond length estimates from Franck-Condon factor calculations are also provided. Possible electronic symmetries for the excited states are proposed using angular momentum and long-range interaction theory arguments.
