    名称:
    Dissociation of Kr+2, N2Ar+, (CO)+2, CH+5, and C2H+5 ions drifting in He
    摘要:
    Rate coefficients for the dissociation of Kr+2, N2Ar+, (CO)+2, CH+5, and C2H+5 ions in collisions with He have been obtained in a drift tube experiment as dependent on the mean relative kinetic energy in the center-of-mass frame Ec in the range from 0.1 to 0.5 eV. The Arrhenius activation energies obtained for dissociation are 1.15, 0.91, 1.1–1.3, 1.1–1.4, and 1.3–1.7 eV for Kr+2, N2Ar+, (CO)+2, CH+5, and C2H+5 ions, respectively. For the thermal energy region, the rate coefficients for the same processes have been calculated from three-body association rate coefficients reported in the literature, equilibrium constants, and known thermodynamic quantities. The values of the dissociation rate coefficients obtained cover a range of 15 to 50 orders of magnitude. The present data indicate that the internal temperature Ti of the drifting ions is in close equilibrium with Ec, i.e., Ec=3/2.kBTi.

    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

    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)+
