Notes:
The absorption (scattering depletion) spectrum and resonance Raman spectrum for Ru2 in an argon matrix prepared by the mass-selected ion deposition technique have been obtained. The absorption spectrum in the visible region shows a single broad transition centered at 470 nm. Resonance Raman spectra, obtained by excitation into this band with dye laser radiation, display a single sharp progression with lines at 343.8(26) cm−1, 681.6(32) cm−1, 1017.5(26) cm−1, 1350.2(25)cm−1,and 1678.9(8) cm−1. These data give ωe=347.1±0.9 cm−1 with ωexe=1.85±1.5 cm−1, leading to a spectroscopic dissociation energy of 2.0±0.2 eV. Sidebands in the Raman spectra are indicative of a weak coupling (Huang–Rhys factor, S∼0.1–0.7) between the dimer and the phonons of the argon host. © 1997 American Institute of Physics.
