High Resolution Optical Spectroscopy of mer-[Cr(dpt)(Gly-Gly)]ClO₄


Abstract

The highly resolved absorption spectra of mer-[Cr(dpt)(Gly-Gly)]ClO4·H2O [dpt = di(3-aminopropyl)amine, H2Gly-Gly = glycylglycine] have been measured between 13000 cm-1 and 50000 cm-1 temperatures down to 2 K. The vibrational intervals were extracted by recording emission and far-infrared spectra. The characteristic infrared bands in meridional isomer were discussed. The four-teen electronic origins due to spin-allowed and spin-forbidden transitions were assigned. With the use of this electronic transitions, a ligand field optimization based on the exact known ligand geometry have been performed to determine more detailed bonding properties of Gly-Gly and dpt ligands. It is confirmed that the peptide nitrogen of the Gly-Gly has a weak π-donor property toward chrornium(Ⅲ) ion.
