Summary The FT-IR/FT-FIR spectra of powders of Nd2−x Ce x CuO4 and La2−x Sr x CuO4 solid solutions and of RBa2Cu3O7−x 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 done. An empirical assignment of the observed bands is proposed on the basis of the factor group analysis and of a discussion of the internal vibrational structure of the CuO x sheets and chains.
