Infrared absorption spectra of Nd2\_~CexCuO4 and R2CuO4 (R=Pr, Nd, Sm, and Gd) have been measured in the energy region between 250 and 800cm-]at room temperature. For Nd2-xCexCuO4 , it is found that the mode at about 350cm-1, which is the vibration of oxygen in the R-O layers along the a-axis, disap
