Abstract
We present a resonance Raman investigation of the lowest energy dipole-allo wed absorption band of [Au-2(dcpm)(2)](ClO4)(2) (dcpm bis(dicyclohexylphosp hine)methane). The resonance Raman spectra provide the first experimental p roof of the 5d sigma* --> 6p sigma electronic transition in dinuclear gold( I)-phosphine compounds. A resonance Raman intensity analysis of the spectra allows estimation of the structural changes of the [d sigma*p sigma] excit ed states relative to the ground state.
