Abstract: Optical and magneto-optical properties of cerium compound CeS are studied using the spin-and-orbitally polarized fullpotential linear muffin-tin orbital (LMTO) method. The diagonal and off-diagonal conductivity tensor elements are calculated from self consistent electronic band structure theory over the full frequency range studied experimentall. We have compared the optical part of the conductivity with available experimental data and previous investigations of other compounds. We have found that while overall agreement ofthe band theory is quite good, it fails to place f-electrons correctly within the spectrum because of its inability to include correlation effects.
