    一些卤代烷离子的碎裂机理和能量学
    摘要:
    碘乙烷、1-溴丙烷、2-溴丙烷、1-碘丙烷和 2-碘丙烷的卤素损失已通过电子-离子重合技术和亚稳态转变的观察进行了研究。分解曲线的分析和停留时间的研究给出了卤素损失的零开尔文阈值,并表明了动力学偏移的大小。碘乙烷的碎裂起点位于 Franck-Condon 间隙。发现丙基卤化物的零开尔文阈值位于或刚好高于母离子的上自旋轨道水平。所有的丙基卤都表现出单分子亚稳态转变。在裂解开始时,2-卤代丙烷离子的碎片动能可以忽略不计,而 1-卤代丙烷产生具有 100-200 meV 动能的二级丙基离子。已经确定,在这种碎裂-异构化过程中必须克服潜在障碍,分析表明存在不同于传统 QET 的动态机制,例如,振动模式的弱耦合。2-卤代丙烷碎裂阈值的分析得出丙烯的质子亲和力的准确绝对值,室温下为 751.4 +/- 2.9 kJ/mol。该值与基于各种相对测量的质子亲和度标度中固有的一些差异相协调。在室温下为 9

    A flowing afterglow-selected ion flow drift tube has been used to measure the rate coefficients and product ion distributions for reactions of H 3 O + , N 2 H + , and H 3 + with a series of 16 alkanes, alkenes, alkynes, and aromatic hydrocarbons as well as acrylonitrile, pyrrole, and pyridine. Exothermic proton transfer generally occurs close to the collision rate. The reactions of H 3 O + are mostly
    流动余辉选择离子流漂移管已用于测量 H 3 O + 、N 2 H + 和 H 3 + 与一系列 16 种烷烃、烯烃、炔烃和芳香烃以及丙烯腈、吡咯和吡啶。放热质子转移通常发生在碰撞速率附近。H 3 O + 的反应大多是非解离的,H 3 + 的反应大多是解离的,但许多反应,特别是N 2 H + 的反应,既有解离通道,也有非解离通道。解离通道主要导致小烃和甲苯中的H 2 和/或CH 4 损失、丙烯腈中C 2 H 2 的损失和吡咯中HCN 的损失。对于苯、吡啶和较大的芳烃,仅观察到非解离质子转移。N 2 H + 与丙烯和丙炔反应的漂移管研究表明,反应物离子中能量的增加会增强碎片化。还研究了一些 D 3 + 反应,结果表明 H 3 + 与不饱和烃 B 的反应通过质子转移进行,形成激发的 (BH + )* 中间体。压力效应表明,一小部分 (BH + )* 中间体分解过快,无法在流管中实现碰撞稳定 (t

    Chemical ionization of alkylbenzenes (PhCxH2x + 1 = M: x = 3–13) by the CH5+, C2H5+, and C3H5+ ions has been studied under a reactant-ion selective mode of an ion-trap type of GC/MS. The dominant product ions for short-chain reagents (x < 7) were [M + H]+, [PhH + H]+, and CxH2x + 1+ ions, produced through proton-transfer to benzene ring. On the other hand, the dominant product ions for long-chain reagents
    已在离子阱型 GC/MS 的反应物离子选择性模式下研究了 CH5+、C2H5+ 和 C3H5+ 离子对烷基苯 (PhCxH2x + 1 = M: x = 3–13) 的化学电离。短链试剂 (x < 7) 的主要产物离子是 [M + H]+、[PhH + H]+ 和 CxH2x + 1+ 离子,通过质子转移到苯环产生。另一方面,长链试剂 (x ≥ 7) 的主要产物离子是 CyH2y + 1+ (y < x) 和 PhCyH2y+ (y ≤ x) 离子。前一种离子是反应物离子对烷基链和/或苯环的攻击而产生的,而后一种离子则是通过反应物离子对烷基链的攻击而形成的。在观察到的分布和计算的热化学数据的基础上,讨论了每个反应中CyH2y + 1+ 和PhCyH2y+ 离子的主要形成过程。

    The reactions of CH3+, CH2F+, CHF2+, and CF3+ with ethene, fluoro-, 1,1-difluoro-, trifluoro-, and tetrafluoro-ethene and with propene, but-1-ene, but-2-ene, and 2-methylpropene have been studied in the gas phase. As well as simple charge exchange, addition reactions were observed in which the initial adduct broke down to yield neutral fragments and ions of either general formula (CnX2n+1)+ or (CnX2n–1)+

  • Ion-molecule reactions of vibrationally state-selected nitric oxide ion(1+) with small alkyl halides
    作者:Thomas Wyttenbach、Michael T. Bowers

    The effects of vibrational excitation in NO+(v = 0-5) on its reactivity with small alkyl halides (CnH2n+1X; n = 1-3; X = Cl, Br, 1) have been investigated under thermal translational conditions. The method combines resonance enhanced multiphoton ionization to form state-selected NO+(v) and Fourier transform ion cyclotron resonance techniques to trap, react, and detect ions. Besides vibrational quenching of NO+(v > 0), which is found to be very efficient with alkyl halides, three reaction channels are observed: charge transfer, halide transfer, and CnH2nNO+ formation. Branching ratios and rate constants have been determined for the different channels as a function of the NO+(v) vibrational energy. Endoergic charge transfer is efficiently driven by vibrational excitation. Halide transfer is the major channel if it is significantly exothermic for NO+(v = 0). If this is not the case, adding vibrational energy in NO+(v) is only marginally effective in driving this channel. The data suggest that rearrangements in NO+-alkyl halide reaction intermediates and in carbonium ions are very rapid. The CnH2nNO+ formation channel is only observed with n-propyl and isopropyl chloride where it is dominant for NO+(v = 0). Increasing vibrational excitation inhibits C3H6NO+ formation. The results are discussed in terms of possible reaction mechanisms.
