The U{sub 2}O{sub 3}{sub ({ital g})} and U{sub 2}O{sub 4}{sub ({ital g})} species have been for the first time identified by Knudsen cell-mass spectrometry and their heats of formation and atomization energies have been tentatively derived. A redetermination of these quantities for the already known UO{sub 3}{sub ({ital g})} and U{sub 2}O{sub 2}{sub ({ital g})} molecules has been also attempted.
