Spectroscopic characterisations of the radical polyinterhalogen molecules IF2 and I2F are reported using anion photoelectron spectroscopy. The corresponding parent anions, IF2- and I2F-, are common products formed in hard Ar-CF3I plasmas and are relevant in the semiconductor manufacture industry. The I2F- species, which is present as the [I-I-F]- isomer, is a "non-classical" polyinterhalogen.

自由基多卤代烃分子的光谱表征。

使用阴离子光电子光谱法报道了自由基多卤代烃分子IF2和I2F的光谱表征。相应的母体阴离子IF2-和I2F-是在硬Ar-CF3I等离子体中形成的常见产物，与半导体制造行业相关。以[IIF]-异构体形式存在的I2F-物质是“非经典”的聚卤素。
