  确定 BrONO 是 Br 与 NO2 气相反应的主要产物

  摘要：

  在与 FT-IR 光谱仪连接的环境室中，已在 215 至 300 K 的温度下对 Br 原子与 NO2 的气相反应产物进行了定量测定。发现反应的主要产物（产率 > 75%）是 BrONO 的顺式异构体，通过其在 1660 cm-1 处的 NO 拉伸基数对其进行鉴定和量化；这代表了该物种的第一次气相检测。尽管快速热分解回 Br 和 NO2 使其无法在室温下检测（寿命 < 1 s），但在 263 K 及以下的温度下检测到 BrONO。 BrONO 异构化为 BrNO2 被发现是 BrONO 在低温下的重要命运温度。发现该过程的速率系数随着压力的降低而增加，这表明过程是非均质的。在 700 托时，

  Properties of Pure Nitryl Bromide. Thermal Behavior, UV/Vis and FTIR Spectra, and Photoisomerization to trans-BrONO in an Argon Matrix

  摘要：

  BrNO2 is produced by the heterogeneous reaction of CINO2, highly diluted in He, with an aqueous bromide solution and subsequent trapping at -155 degrees C. The crude product is purified by trap to trap condensation and fractional sublimation in vacuo. At 300 K and a pressure of 1 mbar, a half-life of about 1 h is observed. The decomposition produces Br-2 and NO2. The UV/vis and IR absorption cross sections of gaseous BrNO2 are determined in the ranges 185-600 nm and 2000-400 cm(-1), respectively. Irradiation of matrix-isolated BrNO2 with visible light causes nearly quantitative isomerization to trans-BrONO, while CINO2 is converted by UV light into a mixture of cis- and trans-ClONO. It is possible to assign all fundamentals of BrNO2 and trans-BrONO by comparison to the respective band position of the analogous molecules XNO(2) and XONO(X=Cl, F).

  fluorescence technique has been employed to investigate the kinetics of reactions of the important stratospheric species bromine nitrate (BrONO2) with ground-state atomic bromine (k1), chlorine (k2), and oxygen (k3) as a function of temperature (224−352 K) and pressure (16−250 Torr of N2). The rate coefficients for all three reactions are found to be independent of pressure and to increase with decreasing

  scrambling in the reaction between BrNO and (18)O(3) as well as in the gas phase equilibrium BrNO + NO(2) right harpoon over left harpoon BrNO(2) + NO are investigated. 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. Photolysis of matrix-isolated BrNO(2) at different wavelengths leads to a

  The heterogeneous chemistry of HBr and HF was studied on glass and ice surfaces at 200 K. Physical and reactive uptake were investigated using a cylindrical fast-flow reactor in conjunction with a chemical-ionization mass spectrometer. HF exhibited no measurable uptake on ice or NAT nor did it significantly react with ClONO2 or HOCl. It is inferred that HF would be unreactive on polar stratospheric cloud particle surfaces. Physical adsorption or absorption of HBr was observed onto glass, adsorbed H2O layers on glass, and ice. For the relatively high [HBr] used, a very large uptake by ice was observed, and we detected no saturation of the surface. HBr reacts efficiently with ClONO2, Cl2, and N2O5, especially on ice and nitric acid ice surfaces. BrCl was observed as the primary product for the reaction HBr + ClONO2. The products HCl and Br2 were observed for the reaction of HBr with Cl2. On the basis of these results, it is likely that HBr would be processed efficiently on ice particles.

  UV absorption cross-sections for cis-BrONO in the gas phase have been measured over the wavelength range 100-365 nm. Absorption measurements were made following cw photolysis of Br-2 in Br-2/NO2/N-2 mixtures in a 100 cm long temperature-regulated absorption cell. The cis-BrONO absorption spectrum shows two maxima in this wavelength range: at 228 nm (2.7 X 10(-18) cm(2) molecule(-1)) and 316 (0.41 x 10(-18) cm(2) molecule(-1)), cis-BrONO absorption cross-sections were determined relative to BrNO2.
