Resumen
Raman and infrared spectra of polycrystalline6Li2C2O4 and7Li2C2O4 have been investigated in the wavenumber region from 1,800 to 40 cm-1. The internal C2O4 -2 vibrations have been studied on the basis of a D2h molecular structure and the correlation field splittings have been found to be about 40 cm-1 for the stretching modes and about 15 cm-1 for the bending modes. The external vibrations of the Li+ and C2O4 -2 sites have been discussed by considering the results of the factor group analysis and the6Li/7Li isotope effect on the normal vibrations. © 1980 Springer-Verlag. 111 6 1265 1272
