Previous Raman studies of the Bi-Sr-Ca-Cu-O system have provided an abundance of interesting results including the existence of an electronic continuum which redistributes below {ital T}{sub {ital c}}, an anomalous phonon renormalization effect, and Fano antiresonance behavior of the 290-cm{sup {minus}1} vibrational mode. We attempt in this paper to determine what connection these features may have to the superconducting behavior of this compound. In order to draw such conclusions a systematic study has been carried out on numerous Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{Delta}} samples. Our Raman investigations indicate that it is the continuum redistribution and a linear low-energy contribution to the scattering intensity at temperatures {ital T}{much lt}{ital T}{sub {ital c}} that are intrinsic to superconductivity in this system.
