  Temperature dependence of the kinetics of the reaction BO+H₂→HBO+H

  摘要：

  We have measured the rate constant for the reaction of BO with H2 between 690 and 1030 K. The results are compared to transition-state-theory calculations consistent with a revised value for the heat of formation of the product HBO. By scaling the frequency of the doubly degenerate bend of the HHBO transition state in analogy with the isoelectronic HHCN transition state and lowering the calculated barrier from 9.5 to 8.5 kcal/mol, we are able to bring the theoretical and experimental rate constants into excellent agreement. Over the temperature range 300–3000 K, the theoretical rate constant is well represented by k(T)=7.49×10−23 cm3 s−1 T3.53 exp(−1590/T).

  The reaction rates of atomic boron with various epoxides have been measured in a flow tube apparatus. The bimolecular rate constants, in units of cm3 molecule−1 s−1, are: 1,2-epoxypropane (8.6 × 10−11 ), 1,2-epoxybutane (8.8 × 10−11), 1,2,3,4-diepoxybutane (5.5 × 10−11), 1-chloro-2,3-epoxypropane (5.7 × 10−11), and 1,2-epoxy-3,3,3-trichloropropane (1.5 × 10−11).

  Excimer laser photolysis of diborane and laser-induced fluorescence of BH have been used to measure rate constants for the reactions of BH with NO and C2H4 at total pressures near 1 Torr, over the temperature range 250–350 K. Upper limits were obtained for the rate constants for reactions of BH with O2, CO, CH4, and C2H6. Experiments with different buffer gases show no effects that can be attributed

  准分子激光的乙硼烷光解和BH的激光诱导荧光已用于测量BH与NO和C 2 H 4在总压力接近1 Torr的情况下在250–350 K的温度下的反应速率常数。获得BH与O 2，CO，CH 4和C 2 H 6反应的速率常数。用不同的缓冲气体进行的实验表明，没有任何影响可归因于缓冲气体在加合物形成过程中充当第三体。对于BH + NO反应，结果与模型相符，在该模型中，通过捕获在偶极-偶极电势中的离心势垒上而形成的中间HBON *会在皮秒级的时间内重新排列，从而得到产物BO和NH。

  The BNNO and AlNNO molecules were prepared by the reactions of laser-evaporated boron and aluminum atoms with nitrous oxide molecules in solid argon, and were identified on the basis of isotopically substituted infrared absorptions as well as theoretical calculations. Both molecules were predicted to have a 2A′ ground state with a zigzag geometry. The N2O subunit in BNNO is highly activated with a
