Resumen:
   The powder FTIR and Raman spectra of the new isotypic diarsenates RbScAs2O7, TlScAs2O7 and       (NH4)ScAs2O7 are discussed with a factor group analysis, on the basis of their known structural characteristics. The spectroscopic behavior clearly reflects all the structural peculiarities and also confirms the rotational quenching of the NH4(+) cation in (NH4)ScAs2O7. The crystal structure of TlScAs2O7 is also reported for the first time and is briefly discussed.
