    Energy partitioning in two kinds of NO molecules generated from the reaction of O(1D) with N2O: Vibrational state distributions of “new” and “old” NO’s
    摘要:
    The reaction of O(1D) with N2O produces two kinds of NO molecules, the “old” one which originally exists in N2O and the “new” one which includes the attacking O atom. Using the isotopically labeled reagent, we determined the vibrational state distributions of these NO’s (X 2Π; v=0–17) separately. To obtain the distributions, two types of experiments were performed with the laser-induced fluorescence (LIF) technique via the NO A←X and B←X transitions. First, the relative populations of NO molecules (the sum of the two kinds of NO’s) in v=0–11 levels were measured with unlabeled reagents. Then, isotopically labeled reaction, O18(D1)+N216O→N18O+N16O, was utilized to determine the relative ratio between the two kinds of NO’s in the vibrational levels of v=0–5 and 12–15. Combining the above results with previously determined vibrational state distribution of NO in high vibrational levels (v=11–17) [J. Chem. Soc., Faraday Trans. 94, 1575 (1998)], we were able to obtain a complete set of vibrational state distributions. It was found that the old NO dominantly populated in v=0 and 1 whereas the new NO extended its population toward higher vibrational levels (v=4–15). However, in high vibrational levels, the old NO still have a considerable population due to the rapid energy transfer to the old NO. The observed efficient energy transfer to the old NO is attributed to the absence of light atoms in the present reacting system. Compared with the system including hydrogen atoms, the state density and the momentum coupling among the vibrational modes are much larger and accelerate the energy redistribution in spite of the short lifetime.

    固体氧气中693 nm处的臭氧光解。臭氧重整中的同位素效应
    摘要:
    结合了693 nm激光照射和红外吸收光谱技术,在10 K的天然氧气基质中研究了可见光区域中18 O 3(完全取代的臭氧或888)的光解离。臭氧888被转化为(不对称和对称的)668和686种,它们通过将18 O与16交换而进一步转化为正常的666种。O原子。888的整体光解离是一阶过程,并提出了一个合理简单的模型,该模型可以令人满意地重现观察到的动力学结果。光解动力学速率常数的值表明可见光带的吸收截面相对于气相中的吸收截面有所增加。实验表明,在18 O氧原子与基质16 O 2分子重组期间,相对于对称物种686,不对称668物种的形成速率增加。

    quantum-chemical calculations. These calculations using density-functional theory (B3LYP/aug-cc-pVTZ) predict four stable isomers of OCS(2): O(CS(2)), SSCO, OSCS, and SOCS, listed in order of increasing energy. According to calculations, O(CS(2)) has a cyclic CS(2) moiety and is the most stable isomer of OCS(2). OSCS is planar, with bond angles angle OSC congruent with 111.9 degrees and angle SCS congruent with

    The matrix isolation technique, combined with infrared spectroscopy and twin jet codeposition, has been used to characterize intermediates formed during the ozonolysis of 2,3-dimethyl-2-butene (DMB). Absorptions of early intermediates in the twin jet experiments grew up to 200% upon annealing to 35 K. A number of these absorptions have been assigned to the elusive Criegee intermediate (CI) and secondary
    基质分离技术与红外光谱法和双喷射共沉积技术相结合,已被用于表征2,3-二甲基-2-丁烯(DMB)臭氧分解过程中形成的中间体。在双射流实验中,退火至35 K时,早期中间体的吸收量增长了200%。其中许多此类吸收物已分配给DMB难以捉摸的Criegee中间体(CI)和次要臭氧化物(SOZ),以前未观察到瞬态物质对于这个系统。与早期研究一致,还观察到主要的臭氧化物(POZ)。在λ≥220至≥580 nm的辐射下探索了这些产物谱带的光解构的波长依赖性。合并的射流(流动反应器)实验生成了DMB的“晚期”稳定氧化产物。d = 0至-11 cm),然后到达冷室进行光谱检测。18 O和加扰的16,18 O同位素标记实验以及B3LYP / 6-311 ++ G(d,2p)水平的理论密度泛函计算进一步支持了DMB臭氧分解过程中形成的中间体的鉴定。

For the equilibrium constant a lower limit of K(298) >/= 1 x 10(-)(3) is deduced from infrared measurements. A detailed IR and Raman study on BrNO(2) is performed.

    investigated at low temperature in an argon matrix. Formation of stable SO3 occurs from the reaction between SO2 and O(1D) and also by oxygen atom transfer within the SO2:O3 complex. Use of isotopic SO2 species led to unusual observations suggesting that photooxidation of SO2 proceeds via an intermediate species, namely, OSOO; this trioxide sulfur isomer transforms into SO3 by tunneling. In the gas phase
