摘要：

Cadmium-rare earth Cd0.25RE0.5 square 0.25MoO4 molybdates, where RE = Pr-Dy, have been prepared and characterised by powder XRD analysis and spectroscopic studies. IR and Raman spectra at room temperature have been measured in the MIR and FIR ranges. The correlation between the lattice parameters and spectroscopic data has been discussed in terms of factor group analysis. The dependences between the RE3+ ionic radius, atomic mass and IR and Raman wavenumbers have been discussed. (C) 2013 Elsevier B.V. All rights reserved.
