Five high-oxidation-state metal oxide fluorides, MnO3F, ReO3F, ReO2F3, ReOF5 and ReOF4 have been isolated as molecular species in inert-gas matrices at low temperatures, and studied by IR and UV/VIS spectroscopy. In particular, the electronic spectra are described and the principal charge-transfer bands assigned using the optical electronegativity model. This suggested that a new value for χopt(F–)
低温下已在惰性气体基质中分离出五种高氧化态金属氧化物
氟化物MnO 3 F,ReO 3 F,ReO 2 F 3,ReOF 5和ReOF 4作为分子种类,并通过IR和UV / VIS光谱学。特别是描述了电子光谱,并使用光学电负性模型分配了主要的电荷转移带。这表明,对于χ一个新的值选择(F - )的3.6是适当的过渡金属氧化物
氟化物。
