    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
    激光闪光光解-共振荧光技术已被用于研究重要的平流层物种硝酸盐 (BrONO2) 与基态原子 (k1)、 (k2) 和氧 (k3) 作为函数的反应动力学温度 (224−352 K) 和压力 (16−250 Torr of N2)。发现所有三个反应的速率系数都与压力无关,并且随着温度的降低而增加。以下 Arrhenius 表达式充分描述了观察到的温度相关性(单位为 10-11 cm3molecule-1s-1):k1 = 1.78 exp(365/T)、k2 = 6.28 exp(215/T) 和 k3 = 1.91 exp(215 /T)。报告的速率系数的准确度估计为 15-25%,具体取决于速率系数的大小和温度。与原子氧的反应是海拔 25 公里以上硝酸溴的重要平流层损失过程;如果分配是为了……这个反应应该包括在平流层化学模型中。

    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
    BrNO和O(3)在低压下(<10 mbar)之间的气相反应导致以约60%的收率形成BrNO(2)。以这种方式制备了(15)N-和(18)O-标记的BrNO(2)。另外,还表明,BrNO(2)也是通过在气态BrNO与掺杂有H(2)O(2)的固体硫酸之间进行的异质低温反应而形成的。可以假设在平流层条件下可以类似的方式形成BrNO(2)。研究了在BrNO与(18)O(3)之间的反应以及在气相平衡中的BrNO + NO(2)右鱼叉在左鱼叉BrNO(2)+ NO上的同位素加扰。对于平衡常数,从红外测量值推导出K(298)> / = 1 x 10(-)(3)的下限。对BrNO(2)进行了详细的IR和拉曼研究。基质分离的BrNO(2)在不同波长下的光解导致顺式和反式BrONO的混合物。BrNO(2)(6个基本原理,7个组合),顺式BrONO(5个基本原理,1个泛音)和反式BrONO(4个基本原理,8个

    first gas-phase detection of this species. Although rapid thermal decomposition back to Br and NO2 precludes its detection at room temperature (lifetime < 1 s), BrONO was detected at temperatures at and below 263 K. Isomerization of the BrONO to BrNO2 was found to be an important fate of BrONO at low temperatures. The rate coefficient for this process was found to increase with decreasing pressure, indicative
    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 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 Br 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,

    A method for the synthesis of gaseous BrNO2 at concentrations of the order of 10-9 mol/cm3 at atmospheric pressure is described, based on the heterogeneous reaction of ClNO2 with aqueous bromide solutions. We measured the gas-phase infrared absorption cross sections in the range 700−1800 cm-1. The matrix isolation spectrum was recorded for identification by comparison with literature data.
