Analysis of the E-X and C-X band system isotopically enriched of Ag2

Abstract The high-dispersion spectra of E - X and C - X systems of isotopic Ag 2 molecules were investigated in the region 247–271 nm. The vibrational numbering is determined by measuring the isotope displacements in the bandheads among 107 Ag 2 , 107 Ag 109 Ag, and 109 Ag 2 . Molecular constants of the states involved are presented.
