Thermal oxidation of trace amounts of curium hydride yields a volatile form of CmO2 and the previously unknown trioxide CmO3. They were separated by gas thermochromatography. Under the experimental conditions, the maxima of the deposition zones of Cm oxides on the surface of the quartz column were at 550 ± 25 and 390 ± 25°C, respectively. The calculated enthalpies of adsorption on quartz (kJ mol−1) were 185 ± 25 (for CmO2) and 157 ± 25 (for CmO3). Lower volatility of Cm di- and trioxide… Expand
Molecular oxides of high-valent actinides

Quantum chemical calculations and experimental investigations of molecular actinide oxides.
TLDR
The available experimental and theoretical information on gaseous actinide oxides covering both the neutral and the ionic species are reviewed and reliable knowledge of either parameter can enable confident prediction of the other. Expand

TLDR
The clarified electronic structures of the investigated AnO3 molecules confirmed the pentavalent character of Am and Cm in their trioxides in contrast to the hexavalent characters of U, Np, and Pu. Expand
Chemical bonding and effective atomic states of actinides in higher oxide molecules
The new concept of atoms in compounds (AiC) is used to derive effective atomic configurations of plutonium and transplutonium elements in higher oxide molecules from the results of DFT calculations.
