Cuprate superconductivity: some spectroscopic, structural, and chemical aspects

S I Vavilov State Optical Institute, Birzhevaya liniya 12, St. Petersburg, 199034, Russian Federation

HTS results obtained by steady-state and time-dependent spectroscopy of spontaneous Raman scattering and by the quantum-beat technique are analyzed. The copper-oxygen chain structure is analyzed by invoking the charge-density-wave concept and the donor-acceptor interaction between chemical-bond partners. Stimulated Raman and hyper-Raman scattering and the low-frequency acoustic spectroscopy of spontaneous Raman scattering are discussed in terms of their prospects for HTS experiments.
