摘要：

Thin films of hydrogenated Bi2Sr2CaCu2O8 show three O-H vibrational absorption bands that shift upon deuteration with frequency ratios vO-H/vO-D≈1.3, as expected for local modes. The band positions indicate that hydrogen atoms may be located at two different sites, namely in CuO2 layers and, for the most part, in BiO double layers. The temperature dependences of these absorption bands give no hint of any direct interactions between the O-H vibrational modes and the superconducting phase transition. © 1990 Springer-Verlag.
