  Chemistry of CFn+ (n = 1-3) ions with halocarbons

  摘要：

  The gas-phase reactions of CF+, CF2+, and CF3+ with the halocarbons CF3Cl, CF3Br, CF3I, CF4, and C2F6 have been studied using a variable-temperature-selected ion flow tube (VT-SIFT) instrument at 300 and 496 K. The ion CF+ reacts rapidly with CF3X (X = Cl, Br, I) producing the ions CF2X+. In the reaction of CF+ with CF3Cl, CF3+ is also produced as a minor product. Curvature was observed in the pseudo-first-order kinetics plots for the reactions of CF+ with CF4 and C2F6. In both cases the curvature is attributed to the presence of two or more CF+ states (probably vibrational) of differing reactivities toward the perfluorocarbon of interest. This conclusion is supported by our observation of charge transfer from CF+ to NO, a reaction which is endothermic by 15 kJ/mol for the ground state of CF+. CF+ is unreactive with O2, N2, and Xe. The reactions of CF2+ with CF3X yield CF3+ and CF2X+ for X = Cl and Br; for X = I, CF2I+ and CF3I+ are produced. The overall reactions proceed at approximately the collision rate at 300 and 496 K, and the branching ratios are not strongly dependent on temperature. The reactions of CF2+ with CF4 and C2F6 produce CF3+ and C2F5+, respectively. The rate constants decrease significantly with increasing temperature. CF2+ reacts rapidly by charge transfer with NO. The reaction of CF2+ with O2, producing CF2O+, is inefficient. CF2+ is unreactive with N2. CF3+ reacts with CF3X (X = Cl, Br, I) at rates below the collision values, producing a single ionic product, CF2X+. While the rate constants for the reactions of CF3+ with CF3X increase in the series with increasing CF3X mass, the rate constants for reaction with each CF3X decrease sharply with increasing temperature. A mechanism is proposed in which the reaction proceeds on a double-well potential energy surface. No reaction was observed for the CF3+/CF4 system. CF3+ appeared to react very slowly with C2F6 and NO, producing C2F5+ and NO+, respectively, but reactions with impurities in the neutral reagents cannot be ruled out as the source of these ions. CF3+ is unreactive with O2 and N2.

  单色同步辐射光解吸附在Si(111)(7×7)表面的CF3Cl

  摘要：

  我们通过单色同步辐射对吸附分子的光解进行了分析。研究的系统是 CF3Cl 在 30 K 下吸附在 Si(111)(7×7) 上，采用的技术是光电子能谱 (PES) 和光子刺激解吸 (PSD)。在各种光子暴露下的价能级光电发射光谱表明，由入射单色同步辐射光子（hν=98或110 eV）引起的光解效应发生在该吸附的气固系统上。F- 和 F+ PSD 离子产率的变化测量为在三个吸附物覆盖（最低剂量 = 0.3×1015、中等剂量 = 0.8×1015 和最高剂量 = 2.2）下单色 (110 eV) 光子暴露的函数×1015 摩尔/平方厘米）。对于最低 CF3Cl 剂量的表面，F- 和 F+ 产率的光子暴露依赖性显示出以下特征：

  studied that reacts with H3O+ at a measurable rate. All the other reactions take place at or close to the collisional rate, the exceptions being the reactions of N2O+ with C2F4 and C3F8, and CO2+ with C2F4 and C2F6, for which the experimental rate coefficients show marked departures from the collisional values. It is proposed that most of the reactions proceed through a complex intermediate resulting

  Photoionization-yield curves are obtained for the molecule and selected radical ions of C2N2, FCN, ClCN, BrCN, and ICN from threshold to 600 Å. Vibrationally excited states of ions and autoionization of Rydberg levels in the molecules are observed and discussed briefly. The X+ ion thresholds in the heavier cyanogen halides are used to obtain: ΔHf0o (CN) = 101.5 kcal mole−1, ΔHf0o (CN+) = 430.0 kcal mole−1, and I (CN) = 14.2 eV. These are applied to compute ΔHf0o (FCN) = 5.6 kcal mole−1, D (F–CN) = 5.0 eV, I (C2) = 12.15 eV, and other thermodynamic properties. The formation of CN+ from dicyanogen apparently includes about 0.6 eV excess energy near the threshold.
