Abstract

We report absorption ("scattering depletion") spectra and Raman measurements on niobium containing matrix samples prepared by the mass-selected ion deposition technique. Niobium dimer ions, produced by sputtering, were mass-selected with a Wien filter and codeposited with Ar and electrons. Several new dimer absorptions are identified in regions which were previously obscured by intense atomic transitions. Two absorptions are also observed in the region 580 -720 nm, including a vibrational progression with ?e' = 426 (4) cm-1. The Raman excitation profile closely mimics the dimer absorption spectrum. Raman spectra give ?e" 420.5 (5) and ?exe" 0.5 (3) cm-1 ,in good agreement with previous measurements made in Kr matrices.
