  亚稳态N 2簇离子的定量顺序衰减序列（N 2）n + * →（N 2）n -1 + * →…→N 2 +

  摘要：

  首次实验观察到了亚稳态分子簇离子的顺序衰减。N 2团簇离子是通过超音速N 2团簇束的电子碰撞电离产生的，并通过双聚焦扇形场质谱仪（反向几何结构）进行分析。发现亚稳态的N 2簇离子在微秒时间范围内会损失一个以上的N 2分子，并且主要通过连续序列（N 2）n + * →（N 2）n -1 + * →…→N 2 +衰变。在每个连续的衰变步骤中蒸发单个单体。亚稳衰变率详细群集确定大小2⩽ Ñ ⩽6和Ñ = 20介于1个10之间6小号-1和后离子形成所经过的时间强烈地依赖。衰减率显示出准周期模式，与以下假设一致：在采样时间内，多达四个振动量子（存储在群集中的中性N 2分子中）松弛进入群集的声子池。

  The structural and mechanical properties of ion‐beam deposited (B0.5−xSix)N0.5 films (0≤x≤0.5) were characterized by x‐ray photoelectron spectroscopy, infrared absorption experiments, and nanoindentation tests. A single‐layer BN film (x=0) has 70 vol. % in cubic phase (c‐BN), and a hardness of 38 GPa. However, it peeled off very soon after deposition due to the high internal stress. If a buffer layer

• Rotational spectroscopy and molecular structure of 15N2–14N2O
  作者：Helen O. Leung

  DOI：10.1063/1.478321

  日期：1999.3.1

  The rotational spectrum of 15N2–14N2O has been recorded in the 7–19 GHz region with a pulsedmolecular beam,Fourier transformmicrowavespectrometer. An internal motion of the 15N2 subunit has been observed and the nuclear quadrupole hyperfine structurein each internal motion state has been analyzed using the WatsonS-reduced Hamiltonian with the inclusion of nuclear quadrupole couplinginteractions. The spectroscopic constants of the ground internal motion state are not welldetermined since only 4 transitions have been observed, but they are similar to those ofthe excited internal motion state that are determined from the analysis of 14a- and b-type transitions. The rotational andcentrifugal distortion constants (in MHz) for the excited internal motion state areA=12 791.307 0(2),B=2 014.982 4(1),C=1 728.950 45(7),DJ=1.052 5(2)×10−2,DJK=3.933 7(3)×10−1,d1=−1.822(3)×10−3,d2=−1.118(6)×10−3. The nuclear quadrupole coupling constants (in MHz) in the excitedinternal motion state for the terminal 14N nucleus in N2O are χaa=0.3465(4),χbb=−0.7445(5), and χcc=0.3980(5), while those for the central 14N nucleus are χaa=0.1023(9),χbb=−0.2528(8), and χcc=0.1505(8). These spectroscopic constants are consistent with aT-shaped structure, with 15N2 forming the leg of the T. The intermolecular distance is3.691 Å. The 15N2 axis and the 14N2O axis make an angle of 13° and 81° with the intermolecularaxis, respectively. The nuclear quadrupole coupling constants show electric field gradient perturbationin the N2O subunit, with the field gradient at the central nitrogenaffected to a greater extent than that at the terminal nitrogen. This perturbation islikely due to electron charge redistribution in N2O upon complexation with N2.
