The FT-IR/FT-FIR spectra of powders of Nd{sub 2-x}Ce{sub x}CuO{sub 4} solid solutions (x{le}0.25) and of RBa{sub 2}Cu{sub 3}O{sub 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{sub x} structures is given.
