We have observed resonant Raman scattering from the Ag mode of FeS2 (pyrite) for incident laser energies between 2.41 and 2.73 eV, these energies being well above the fundamental gap at 0.9 eV. In contrast to the behavior of the Ag mode intensity, the Eg and Tg modes do not show resonant behavior. A simple two band model which predicts the Raman cross section proportional to |∂χ/∂ω|2 is found to be inadequate to describe the observed intensity variation with the incident laser energy. © 1974.
