    Reactions of O+ N2O at 300 K: The totally labeled experiments
    摘要:
    The tandem flowing afterglow-selected ion flow tube was employed to study the isotopically labeled reactions of O−+N2O→NO−+NO at 300 K. In the reactions of 16O−+15N14N16O, 16O−+14N15N16O and 18O−+14N14N16O, both of the possible NO− products are formed with equal probability, indicating that equilibration is achieved within the reaction complex before dissociation. In the totally labeled reactions of 18O−+15N14N16O and 18O−+14N15N16O all possible NO− products are observed which strongly supports the formation of both trigonal and linear N2O−2 intermediates along the reaction path. The reaction mechanism is discussed and these results are compared with those of other workers.

    摘要:
    AbstractReadily available cyclobutanols having a butyne‐1,4‐diol moiety underwent a sequential regioselective Meyer–Schuster rearrangement and 1,2‐shift, furnishing α‐hydroxy‐α‐vinylcyclopentanones. The reaction mechanism is consistent with the formation of an allenol intermediate that racemizes under the reaction conditions. Subsequent activation of the allenol leads to an enantio‐ and diastereoselective route to this scaffold.magnified image

  • Infrared Spectrum of Hg(OH)<sub>2</sub> in Solid Neon and Argon
    作者:Xuefeng Wang、Lester Andrews

    日期:2005.1.1
    Mercury(II) hydroxide molecules have been prepared upon mercury arc lamp irradiation of Hg, H(2), and O(2) mixtures in solid neon and argon. The strongest three infrared absorptions are identified through isotopic substitution (D(2), HD, (18)O(2), (16)O(18)O) and comparison to frequencies from DFT calculations. The isolated Hg(OH)(2) molecule is stable and has a linear O-Hg-O linkage in a C(2) structure
    (II)氢氧化物分子是在弧灯照射下在固态氖气气中的Hg,H(2)和O(2)混合物辐照后制得的。通过同位素取代(D(2),HD,(18)O(2),(16)O(18)O)并与DFT计算的频率进行比较,可以确定最强的三种红外吸收。分离的Hg(OH)(2)分子是稳定的,并且在具有86度二面角的C(2)结构中具有线性O-Hg-O键。但是,在溶液中,Hg(2+)和2OH(-)可能会形成Hg(OH)(2)中间体,该中间体会消除并沉淀出固态HgO:固态Hg(OH)(2)化合物是未知的。

    the HXeOH molecules isolated in solid Xe at 7 K. Upon the 16O to 18O isotopic substitution, we found experimentally an anomalous shift of the H–Xe stretching vibration frequency of HXeOD and HXeOH. This spectral behavior, when the fundamental frequency shifts up in energy for the heavier oxygen isotope, cannot be understood on the basis of the harmonic approximation for fundamental vibrations, and
    我们研究了在 7 K 下在固体 Xe 中分离的 HXeOH 分子的各种同位素异构体的 IR 吸收光谱。在 16O 到 18O 同位素取代后,我们通过实验发现 HXeOD 和 HXeOH 的 H-Xe 伸缩振动频率的异常偏移。当重氧同位素的基频能量上移时,这种光谱行为不能基于基本振动的谐波近似来理解,并且正常模式之间的非谐波耦合可能是造成这种反常效应的原因。我们的非谐波 CC-VSCF 计算正确地描述了实验观察结果。

    The 18O-exchange reaction between iodate ions and water has been investigated using a rapid chemical-quenching technique. Over the range 2.1 < pH < 12.5 the exchange occurs by hydrogen- and hydroxide-ion catalysed paths according to the rate law (i). At 5 ° C and I= 1.0 mol dm–3(Li[ClO4]) the rate constants are k0 < 0.01 s–1, R/[IO3–]=k0+k1[H+]+k2[H+]2+k3[OH–](i)k1=(3.20 ± 0.11)× 103 dm3 mol–1 s–1
