N2 - Reflectivity spectra of (Formula presented) and (Formula presented) were measured in a wide photon energy region between 5 meV and 30 eV at room temperature. Using the conductivity spectra obtained from the Kramers-Kronig analysis, electronic structures of the manganese oxides were investigated. In particular, the states near the Fermi energy (Formula presented), O 2p and Mn 3d ((Formula presented),(Formula presented)), were studied in detail. It was found that the O 2p band is located closer to (Formula presented) than the Mn (Formula presented) band. For (Formula presented), the filled Mn (Formula presented) band is located closer to (Formula presented) than any other valence band. The (Formula presented)-(Formula presented) Hund exchange energy was found to be about 3.4 eV and the Jahn-Teller stabilization energy (Formula presented) was estimated to be less than 0.5 eV.
