Abstract
Raman scattering spectra have been measured in superconducting samples of the mercury-cuprate homologous series HgBa2Can-1CunO2n+2+x with n = 1, 2, 3. A comparative analysis of these results and the correspondi ng data on thallium-based high-T(c) superconductors is carried out. Al l the observed Raman scattering lines (or frequencies) are attributed to combinations of O1 and O2 oxygen. The Raman scattering spectrum of a precursor of the 1212 phase, Ba2CaCu2O5, has been studied.
