Abstract

The FT-IR/FT-FIR spectra of powders of Nd_2-xCe_xCuO₄ solid solutions (x ≤ 0.25) and of RBa₂Cu₃O_7-y (y = 0.2-0.3) with R = Y, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, and Yb, have been recorded at room temperature. A comparison with the published single crystal IR data is made. An empirical assignment of the observed bands is proposed on the basis of the factor group analysis and a discussion of the internal vibrational structure of the CuO_x structures is given.
