    Bond selectivity in the reaction of NH(a1Δ) with methanol
    摘要:
    Reaction of NH(a 1Δ) with methanol has been studied by a flash photolysis of HNCO at 193 nm at room temperature (298±2 K). Time dependence and relative concentrations for NH, NH2, NHD, CH3O, H, and D are monitored by a laser induced fluorescence (LIF) technique. From the pseudo-first-order analysis of NH(a 1Δ) decay rate, the rate constants for the reactions NH(a 1Δ)+CH3OH→ products (1), and NH(a 1Δ)+CH3OD→products (2) have been determined to be k1=(1.37±0.10)×10−10 cm3 molecule−1 s−1 in the pressure range of 3–20 Torr Ar or 5 Torr He, and k2=(1.33±0.05)×10−10 cm3 molecule−1 s−1 at the pressure of 5 Torr He, respectively. By comparing the LIF intensity of NH(X 3Σ−) in reaction (1) with that in NH(a 1Δ)+Xe reaction system, the contribution of physical quenching in reaction (1) has been evaluated to be less than 2.4%. Also by comparing the LIF intensities of NHD and NH2 in reaction (2) with those in NH(a 1Δ)+D2/H2 reaction systems, the branching ratio between the pathways producing NHD (2b) and NH2 (2c) has been determined to be k(2b)/k(2c)=23±9. It is elucidated that the insertion of NH(a 1Δ) into O–D bond of CH3OD is completely predominant over C–H bond; i.e., the O–D bond is about 69 times more reactive toward insertion of NH(a 1Δ) than a single C–H bond.

  • Gas-phase chemistry of HSiS- and HSiNH-: ions related to silathioformaldehyde and the silaazomethine of formaldehyde

    日期:1993.3
    Anion related to silathioformaldehyde (H 2 Si=S) and the silaazomethine of formaldehyde (H 2 Si=NH) have been prepared and studied using flowing after glow selected ion flow tube techniques. The connectivities of these anions are shown in experimental studies to be [HSiS] - and [HSiNH] - . In addition, ab initio computational studies demonstrate that these are the most stable anion isomers. These anion

    日期:1997.9
    The gas-phase ion-molecule reactions of simple anions (HO−, CH3O−, NH2−) with SO2F2 proceed with rate constants close to the collision limit. The energy surface for the OH−/SO2F2 reaction has been characterized by ab initio calculations using basis functions adapted for a pseudopotential and corrected for anionic systems by the generator coordinate method (GCM) at the QCISD(T)/(ECP/TZV/GCM) level.

    日期:1995.4
    The kinetics of the self-reaction and the reaction with OH of the amidogen radical were studied at 298 K by pulse radiolysis combined with UV detection of NH2 and OH radicals at 597.7 and 309.0 nm. The rate constant for the association reaction of NH2 radicals was found to be pressure dependent in the range 200–1000 mbar of SF6, and by Troe's analysis the following high- and low-pressure limiting rate
