The resonanceRaman spectra of the ground- and lowest excited-states for a series of binuclearcopper(I) complexes with bridging ligands based on 2,3-di-(2-pyridyl)quinoxaline have been measured. Analyses of the ground-state resonanceRaman spectra show strong enhancement of an inter-ring stretching mode and quinoxaline-based modes; consistent with the Frank–Condon state having bonding changes about
