The spectra of carbonates were measured in mid- and far-infrared region. These spectra show very strong and broad peaks in the far infrared region. The calcite and dolomite have peaks at about 92, and about 63 micrometer, respectively. The unidentified bands of ISO data could be explained including these carbonates. The alteration process from CaO to calcite is investigated with infrared spectra. Adding enough water to CaO, calcite or calcite-like minerals were formed. These process may be clue the formation of carbonates around circumstellars.
Compositional dependence of infrared spectra of carbonates and their precursors
