Abstract
The present work reports an infrared and Raman spectroscopic study of the S rPbP2O7 and BaPbP2O7 orthorhombic diphosphates. The comparison of the vibra tional spectra of the studied compounds, with those of alpha-Sr2P2O7, a-Ba2 P2O7, allowed us to confirm the crystallographic results obtained and prove d the influence of the ionic radius of the alkaline-earth on the frequencie s of the P2O74- vibrations.
