Emission spectrum of rare gas dimers in the vacuum UV regions. III. Ne2

摘要

Emission spectra of the neon dimer have been studied in the VUV region. Liquid nitrogen cooled neon was excited with a Tesla coil or transformer discharge. Three band systems I, II, and III were observed in the 735ndash;1000 Aring; range and classified as produced by electronic transitions to the common ground stateX0+g(1S0) from the three low lying excited states 1u(3P2), 0+u(3P1), and 0+u(1P1), respectively. Evidence for the existence of potential humps in the lowest two upper states were observed and the hump heights were calculated to be 142plusmn;10 and 670plusmn;50 cmminus;1, respectively. Observations of additional spectra, a newly observed emission continuum and two diffuse band groups, are presented.
