Pressed ceramic pellets of the high-temperature superconductor
Bi2Sr2CaCu2O8 (T(c) = 85 K) were investigated by reflectance
spectroscopy in the infrared and visible regions at several
temperatures both below and above the superconducting transition. In
the process of identifying and analyzing vibrational lines in these
samples, two problems arise: diffuse scattering connected with the
grainy surface and a non-conventional baseline caused by intense
absorption of the electronic background present in the infrared region.
After eliminating the effects due to these processes, the temperature
dependence of the vibrational lines can be extracted. It is concluded
that none of the lines behaves in an anomalous way, i.e., no vibration
strongly coupled to the electronic system was found.
