Kamotoïte-(Y), a new uranyl and rare earth carbonate, has been studied by thermal treatment. The mineral has also been characterized by IR spectroscopy and the presence of the bidentate binding of carbonate to uranyl ion has been confirmed. Likewise, the U-O bond lenght in the uranyl group can be estimated by IR measurements.
