Raman spectra of some heavy metal oxalates

AnaC.Gonzalez-Baro, Enrique J.Baran

The Raman spectra of microcrystalline powders of Ag2C2O4, Tl2C2O4 and HgC2O4 are recorded and discussed on the basis of their structural peculiarities and in comparison with the spectra of other previously investigated metallic oxalates. In the case of Tl2C2O4 also IR data were used to complement the spectral analysis.
