Abstract
Polarized single-crystal absorption spectra of [Rh(phpy)2bipy]PF6 at 10K show three origin lines C,D, and N with very sharp vibrational sidebands. From a comparative study of the highly resolved low-temperature absorption spectra of [Rh(phpy)2bipy]PF6, [Rh(phpy)2bipy]BΦ4, [Rh(phpy)2en]PF6 and [Rh(phpy)2en]BΦ4 (en-enthylenediamine, BΦ -4 =tetraphenylborate anion) it can be concluded that the lines C and D correspond to ligand-centered 3ππ*excitations localized on the two crystallographically inequivalent phpy- ligands and that line N can be assigned to an analogous transition on the bipy ligand.
