Abstract
The nature of the visible optical transitions in 1,3-diethynylcyclobutadiene(cyclopentadienyl)cobalt oligomers has been studied by polarized optical absorption and resonance Raman spectroscopy. The transition at 360 nm (the band exhibiting the largest bathochromic shift in the solution spectra of the oligomer series) as well as the feature at 450 nm, which does not show a bathochromic shift, were examined. Both have their transition dipole moment parallel along the π-conjugated electron system. Based on Raman studies this long wavelength transition was assigned as being localized on the butadiyne bridges.
