Spectra of the predissociated 1g state of Xe2 dissociating to

Analysis of the mass-resolved two-photon spectra of jet-cooled ArKr near Kr*(5p) and Ar*(4s)

“…The results here and those obtained for the Xe containing excimers [9][10][11][13][14][15] show that REMPI excitation, TOF mass spectrometry, and polarization measurements are a powerful combination for unraveling the complexities of these molecular systems. It is hoped that our data will prove useful in the interpretation of the rates of energy and population transfers between atomic levels in Ar/Kr gas mixtures in terms of avoided crossings between the potential energy curves of the heteronuclear collision pairs.…”

“…To date, our group has provided detailed vibrational analyses of the single isotopomer spectra of Xe 2 , [9][10][11] Kr 2 , 10,12 KrXe, 13,14 and ArXe 14,15 which were recorded using ͑2ϩ1͒ REMPI/TOF experimental methods. We have for most of the transitions considered, also deduced excited state symmetries from separate REMPI/TOF spectra recorded with circularly polarized light, and excited state bond lengths from Franck-Condon factor calculations.…”

Extreme ultraviolet laser/time-of-flight mass spectra of Kr2 near Kr*(4d,5p′,6s)

“…Details on their construction are available elsewhere. 19,[32][33][34][35][36][37] Each figure was drawn by assuming that the Kr 2 ϩ ion-core state splittings are smaller than energy separations between the j components of Rydberg electron, an assumption which to date has only been confirmed for Xe 2 by dispersive photoelectron spectroscopy. 36,37 Given a molecular state with known dissociation products and binding energy, these diagrams can often be used to assign the excited state value of ⍀.…”

Dissociation dynamics of the low-lying Rydberg states of Xe2: a velocity map imaging study

“…The xenon dimer (Xe 2 ) has been the subject of numerous experimental and theoretical [22][23][24][25][26][27][28][29][30][31] studies owing to its applicability as a gain medium for vacuum ultraviolet (VUV) lasing and as a possible kinetic intermediate in atomic Xe infrared lasers. 14,[32][33][34] Experimental techniques applied to study Xe 2 have included absorption spectroscopy, 1,2,11,35 resonance enhanced multi-photon ionization (REMPI), [3][4][5][6]14,[18][19][20] photoelectron spectroscopy, 7,10,15,16 laser induced fluorescence (LIF), 9,13,17,21 and, recently, velocity map imaging (VMI). 8,36,37 For the most part, these experimental studies have focused on the spectroscopic characterization of Rydberg states which correlate with Xe 5p 6 ( 1 S 0 ) + Xe* products, where Xe* represents excited state xenon in 5p 5 6s, 5p 5 6p, 5p 5 5d, or 5p 5 7s electronic configurations.…”

“…8,10,13,36,37 Spectroscopic investigations particularly pertinent to this study have been reported by Dehmer et al, 3,10 by Gornik et al, 9,21 and Lipson and coworkers. [4][5][6][7]14,15,19 These investigations involved two-photon excitation of Xe 2 Rydberg states observed via photoionization [3][4][5][6][7]10,14,16,19 or fluorescence. 9,21 Two-photon transitions in Xe 2 occur between the X0 electronic ground state and the gerade excited states.…”
