| Abstract: | The interactions between metal ions and carbohydrates are important owing to their possible biological function. Here a series of lanthanide-galactitol complexes were prepared and characterized by Raman spectroscopy. The results show that the Raman spectra of the complexes have been changed substantially. Although the band positions in different lanthanide complexes are similar, those Raman spectra show relatively larger differences. And the influences of different lanthanide ions are shown clearly in the Raman spectra, which reflect the characteristic of every rare earth ion. |
