    摘要 使用带1米长放电室的源调制微波光谱仪观察了SF自由基在2 Π 1 2 状态下的旋转光谱。SF 自由基通过在 OCS CF 4 混合物中的直流放电直接在电池中产生。之前对 2 Π 3 2 状态的微波光谱的测量也扩展到了高 J 跃迁。对所有观察到的谱线进行最小二乘分析得出 B0 旋转常数和 D0 离心畸变常数分别为 16 576.9140(46) 和 0.02924(10) MHz,其中括号中的值表示标准偏差的 2.5 倍。发现 Λ 倍增常数 pv 非常小,为 3.409(44) MHz,并且假设 2Σ+ 和 2Σ- 状态对 Λ 倍增的贡献相互抵消。

  • Elementary reactions of the SF radical. Part 1.—Rate constants for the reactions F + OCS → SF + CO and SF + SF → SF<sub>2</sub>+ S

    DOI:10.1039/f29848001001

    Elementary reactions involving ground-state SF(X2Π) radicals have been studied at 295 K in a discharge-flow system near 1 Torr‡ using mass-spectrometric detection with collision-free sampling. SF radicals were generated by the reaction of F(2PJ) atoms with OCS: F + COS [graphic omitted] SF + CO (1). Rate constants are reported for reaction (1) as well as for the bimolecular disproportionation of SF

    Reactive scattering of F atoms with OCS molecules has been studied at an initial translational energy E≈ 30 kJ mol–1, using a supersonic beam of F atoms seeded in He buffer gas generated by a high-pressure microwave discharge source. The centre-of-mass differential cross-section peaks in the forward direction with a subsidiary peak in the backward direction of relative height ca. 0.75 ± 0.2. The product

    molecular SO 2 F 2 + ion, whose capability of activating strong H X bonds (X = C, N, O) is ascribable to the high spin density located on the oxygen atoms, in line with literature reports. Among the ions produced by electron ionization of SO 2 F 2 , the FSO x + ( x = 0–2) ions are capable of activating the H NH 2 bond of ammonia. Theoretical investigation revealed that NH 3 activation by SF + requires
    摘要 通过离子阱质谱和从头计算研究了硫酰氟的气相离子化学。大气相关离子与中性 SO 2 F 2 的反应主要通过解离电子转移导致 SO 2 F 2 消耗。在少数情况下,会调用涉及 F-抽象的不同反应机制,因为尽管电子转移通道是吸热的,但仍观察到离解离子产物。从头算计算揭示了分子 SO 2 F 2 + 离子的近乎完美的失谐结构,其激活强 HX 键 (X = C, N, O) 的能力归因于位于氧原子上的高自旋密度,直线与文献报道。在 SO 2 F 2 电子电离产生的离子中,FSO x + ( x = 0–2) 离子能够激活氨的 H NH 2 键。理论研究表明,SF + 对NH 3 的活化需要沿反应途径进行三线态到单线态的转化。这种转化预计会很快,可以想象的反应速率决定步骤是随后的分子内氢迁移。
  • Chemiluminescence spectra of the reactions of Li, Na, K with SF6 and Na with SF4 and the dissociation energy of SF
    作者:W. Berneike、U. Kreutle、H. Neuert

    日期:1980.12
    The chemiluminescence spectra of the reactions of Li, Na, and K with SF6 and SF4 are recorded. Beside intense atomic spectra of the alkali atoms and a “quasi-continuum”; a weak band system at λ > 350 nm was observed with the same structure for all reactions. These bands are assigned to the emission from SF∗. The limit of the structure at 350 nm corresponds well with Do(S-F) = 3.52 ± 0.07 eV.

  • Rate constants, branching fractions, and energy disposal for the H+ClO and H+SF reactions
    作者:S. J. Wategaonkar、D. W. Setser
    DOI:10.1063/1.456339
    日期:1989.6
    The H+ClO and SF reactions have been isolated and studied by infrared chemiluminescence in a fast flow reactor. The OH product channel is favored over the HCl channel by a factor of 4.5 and the total rate constant is (7.7±1.9)×10−11 cm3 s−1 for the H+ClO reaction. Both sets of products are accessed from a bound singlet intermediate with HCl+O(3 P) formed by a singlet–triplet surface crossing in the exit channel; the energy disposal is 〈fV (OH)〉=0.45 and 〈fV (HCl)〉=0.31. The H+SF reaction gives only HF+S(3P), but the energy disposal differs dramatically from the HCl channel of the ClO reaction. This difference arises from changes in the thermochemistry, which result in an earlier crossing to the HSF triplet surface followed by release of repulsive energy as the HF separates from the S(3P) atom.
