Abstract Ion-to-molecule equilibria among gaseous iron, uranium, and molybdenum fluorides, and their negative ions, have been studied by Knudsen-cell mass spectrometry with the help of a combined ion source. On the basis of thermochemical quantities, derived by third-law analysis and from the literature for enthalpies of formation of gaseous species, electron affinities have been calculated for a number
摘要 在组合离子源的帮助下,通过 Knudsen-cell 质谱法研究了气态铁、铀和钼氟化物及其负离子之间的离子-分子平衡。在热化学量的基础上,通过第三定律分析和气体物质形成焓的文献,计算了许多分子的电子亲合力:FeF3,(349 ± 13) kJ·mol-1;FeF3,(349 ± 13) kJ·mol-1;UF5,(361±21)kJ·mol−1;UF6,(488±19)kJ·mol−1;MoF5,(335±17)kJ·mol−1;MoF6,(369±18)kJ·mol−1;Mo2F9,(350±40)kJ·mol−1;和 Mo2F10, (363 ± 25) kJ · mol−1。
