Resonance Raman Investigation of the Au(I)−Au(I) Interaction of the 1[dσpσ] Excited State of Au2(dcpm)2(ClO4)2 (dcpm = Bis(dicyclohexylphosphine)methane)
We present a resonance Raman investigation of the lowest energy dipole-allowed absorption band of [Au2(dcpm)2](ClO4)2 (dcpm = bis(dicyclohexylphosphine)methane). The resonance Raman spectra provide the first experimental proof of the 5dσ* → 6pσ electronic transition in dinuclear gold(I)−phosphine co...

| Zusammenfassung: | We present a resonance Raman investigation of the lowest energy dipole-allowed absorption band of [Au2(dcpm)2](ClO4)2 (dcpm = bis(dicyclohexylphosphine)methane). The resonance Raman spectra provide the first experimental proof of the 5dσ* → 6pσ electronic transition in dinuclear gold(I)−phosphine compounds. A resonance Raman intensity analysis of the spectra allows estimation of the structural changes of the [dσ*pσ] excited states relative to the ground state. |
