The absorption and resonance Raman spectra of yttrium dimers (Y2) in argon matrices have been measured for the first time. The absorption spectrum (scattering depletion spectrum SDS) shows a weak, broad transition centered near 485 nm. Resonance Raman spectra obtained by exciting into this absorption band with several visible laser lines (465.5√496.5 nm) give a single, sharp progression with up to ten Stokes transitions. These data give we=184.4(4) cm-1, with we xe=0.30(3) cm-1, leading to a spectroscopic dissociation energy of De=3.5(4) eV. Comparison of our results with several ab initio calculations adds confirmation to the assignment of the ground state of Y2 to be 1∑g+ state.
