摘要：

We report absorption and Raman spectra for cobalt dimers in an argon matrix prepared by the mass-selected ion deposition technique. A weak dimer absorption band was found between 425 and 485 nm. Resonance Raman spectra (obtained by exciting between 457.9-488.0 nm) give ω″e = 296.8(54) cm-1 with ωeχ″e = 2.2(8) cm-1. The dicobalt data are discussed in terms of results from recent photodetachment experiments which suggest a changeover from d-d bonding to s-s bonding along the series Fe2→Cu2. © 1994 American Institute of Physics.
