  与碳酰氟、F2CO 的离解电子连接

  摘要：

  摘要 低能电子附着在气相碳酰氟 F2CO 上，已经通过交叉电子-分子束实验在 0 到 30 eV 的电子能量范围内进行，能量分辨率约为 0.5 eV。由于 F- 和其他两种阴离子物质，在 19 amu 处观察到最强的信号，在 38 和 47 amu 处的强度较低，分别分配给 F2- 和 COF-。测量了三种阴离子的阴离子效率曲线。产物阴离子（F-和COF-）主要在由简单键断裂产生的低能量区域中观察到，而F2-是由两个键断裂产生的，并具有进一步的结构和电子重排。为了补充实验结果，已经对 F2CO 的电子特性进行了量子化学计算。

• Gas‐phase reactions of oxide and superoxide anions with CF₄, CF₃Cl, CF₃Br, CF₃I, and C₂F₄ at 298 and 500 K

  Rate constants and product branching fractions have been measured for the gas-phase reactions of oxide (O−) and superoxide (O2−) anions with the halocarbons CF4, CF3Cl, CF3Br, CF3I, and C2F4 using a variable temperature–selected ion flow tube (VT–SIFT) instrument operated at 298 and 500 K. The reactions of O− with CF3X (X=Cl, Br, I) are fast and produce F−, XF−, and XO− for all X. For CF3Cl and CF3Br, X− is also formed. For CF3I, CF3− and IOF− are minor products. O− reacts rapidly with C2F4 producing F− as the major ionic product, along with contributions from reactive detachment and minor formation of FCO−, CF3−, and C2F3O−. The reaction of O2− with CF3Cl is slow, and both clustering and X− formation were observed. For CF3Br and CF3I, the reactions with O2− are fast, and nondissociative charge transfer was observed in addition to X− formation. O2− reacts rapidly with C2F4 by reactive detachment, in addition to producing F− as the major ionic product with smaller amounts of F2−, FCO−, FCO2−, CF3O−, and C2F4O−. O− and O2− were both found to be unreactive with CF4 at 298 and 500 K. The efficiencies of the reactions of both O− and O2− with CF3X are greater for the heavier halides at both 298 and 500 K. The rate constants for the reactions of O2− with CF3X appear to correlate both with the rates of thermal electron attachment to CF3X and with the electron affinities of CF3X, indicating that the O2−+CF3X reaction mechanism may involve initial electron transfer followed by dissociation. Thus the negative electron affinity of CF3Cl may explain the very slow rate for reaction with O2− despite the available exothermic pathways.

  Abstract Low energy electron attachment to gas phase carbonyl fluoride, F2CO, has been performed by means of a crossed electron-molecular beam experiment in an electron energy range from 0 to 30 eV with an energy resolution of ∼0.5 eV. The most intense signal is observed at 19 amu due to F− and two other anionic species with lower intensities at 38 and 47 amu assigned to F2− and COF−, respectively
