摘要：

A mass spectrometric study of SeO2 and SeO3 sublimation from a Knudsen cell has established SeO2(g) and SeO3(g) as the major vapor species. The heats of sublimation are: SeO2(s) = SeO2(g) ΔH°298 = 25 ± 3·0 kcal mole-1SeO3(s) = SeO3(g) ΔH°298 = 11 ± 2·0 kcal mole-1. A search for complex molecular species showed ∼1% dimer in the equilibrium vapor over SeO2 at 400°K. © 1969.
