A theory for the electronic contribution to Raman scattering in anisotropic superconductors is presented. It is shown that Raman scattering can provide a wealth of polarization-(symmetry-) dependent information which probes the detailed angular dependence of the energy gap. Using a model band structure, the symmetry-dependent Raman spectra are calculated for d{sub x{sup 2}{minus}y{sup 2}} pairing and compared to the data taken on Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. Favorable agreement with the symmetry-dependent electronic spectra is shown. Further, the impurity dependence of theory is calculated, which provides an unique test of d{sub x{sup 2}{minus}y{sup 2}} pairing.
