    用腔衰荡激光光谱研究 IO 自由基与二甲基硫醚反应的温度和压力依赖性
    摘要:
    使用腔衰荡激光光谱研究了 IO 自由基与二甲基硫醚的反应。反应速率常数显示出温度和压力依赖性。在 100 Torr 总压下,反应已达到其高压极限,在 298 K 时反应速率常数为 (2.5 ± 0.2) × 10-13 分子-1 cm3 s-1。在 273-312 K 区域,反应具有负活化能 (Ea = -18.5 ± 3.8 kJ mol-1)。讨论了这些发现的大气影响。根据这些新数据,IO 对 DMS 的氧化可以与海洋边界层中羟基自由基的氧化竞争。引用的不确定性是回归分析的一个标准偏差。

    Laser induced fluorescence of IO radicals and rate constant for the reaction of IO+NO
    摘要:
    The first observation of laser-induced fluorescence of the IO free radical in the gas phase is reported. The source of ground-state IO (X 3Π3/2) radicals was the photolysis of the O3–HI mixture by KrF (248 nm) and N2O–HI mixture by ArF (193 nm) excimer laser radiation. Laser excitation spectra involving the vibrational levels of the A 2Π3/2 state were measured, using excitation wavelengths varying from 440–470 nm from a YAG-pumped dye laser. The laser excitation spectra of the 2-0 and 0-0 band were observed, while the 1-0 band was not observed due to strong predissociation. The lifetimes of v′=2 and v′=0 levels in the A 2Π3/2 state were shorter than 10 ns. This means that predissociation occurs also in both levels. Each rotational level in the v′=2 and v′=0 levels is affected by predissociation; predissociation occurs more strongly in the higher J levels. The rate constant for the reaction of IO+NO→I+NO2 was measured by the addition of NO to the N2O–HI system. The rate constant obtained is (2.8±0.2)×10−11 cm3 molecule−1 s−1, 1.6 times faster than the value reported by Ray and Watson.

  • Rotational spectroscopy of IO X 2Πi
    作者:Charles E. Miller、Edward A. Cohen
    DOI:10.1063/1.1398308
    日期:2001.10.8
    Pure rotational spectra of the IO radical have been observed for vibrational levels up to v=13 in the X1 2Π3/2 state and up to v=9 in the X2 2Π1/2 state. Isotopically enriched I18O rotational spectra have been observed for vibrational levels up to v=5 in both the X1 and X2 states. These are the first high-resolution spectra of any kind reported for the X2 state and greatly extend the available data
    对于在 X1 2Π3/2 状态下高达 v=13 和在 X2 2Π1/2 状态下高达 v=9 的振动能级,观察到 IO 自由基的纯旋转光谱。已观察到在 X1 和 X2 状态下振动能级高达 v=5 的同位素富集的 I18O 旋转光谱。这是针对 X2 状态报告的任何类型的第一个高分辨率光谱,并极大地扩展了 X1 状态的可用数据。两种同位素的数据已同时拟合到具有固定同位素比率的一组 2π 参数。参数之间的同位素关系提供了一种将电子自旋旋转常数 γ 与精细结构离心畸变常数 AD 解相关的方法,并允许首次确定 γ 的有效值。旋转振动常数对应于平衡分子性质 re(X1)=186.762 pm、re(X2)=188.468 pm、ωe(X1)=681.69 cm-1 和 ωe(X2)=645.29 cm-1。这些常数已用于计算 X1 和 X2 Rydber...

    Laser induced fluorescence (LIF) from the (0, 0), (2, 0), (3, 0) and (2, 1) bands of the system of IO was detected. Using LIF detection of IO, the rate coefficients for I + O3 ← IO + O2 (k1) and IO + NO → I + NO2 (k2) reactions were measured between 240 and 370 K to be k1(T) = (2.3 ± 0.7 × 10−11 exp[−(860 ± 100)/T] and k2(T) = (1.02 ± 0.31) × 10−11 exp[(185) ± 70)/T] cm3 molecule−1 s−1.

    Oxygen-iodine lasers that utilize electrical or microwave discharges to produce singlet oxygen are currently being developed. The discharge generators differ from conventional chemical singlet oxygen generators in that they produce significant amounts of atomic oxygen. Post-discharge chemistry includes channels that lead to the formation of ozone. Consequently, removal of I(2P1/2) by O atoms and O3
    当前正在开发利用电或微波放电产生单线态氧的氧碘激光器。放电发生器与常规化学单重态氧气发生器的不同之处在于,它们会产生大量的原子氧。放电后化学物质包括导致臭氧形成的通道。因此,由O原子和O3去除I(2P1 / 2)可能会影响放电驱动的碘激光器的效率。在本研究中,我们使用脉冲激光光解技术测量了O(3P)原子和O3淬灭I(2P1 / 2)的速率常数。发现用O3淬灭的速率常数为(1.8 +/- 0.4)x 10(-12)cm3 s-1,比文献值小5倍。通过O(3P)淬灭的速率常数为(1.2 +/- 0.2)x 10(-11)cm3 s-1。

    The fast reaction of gaseous ozone, O3(g), with aqueous iodide, I−(aq), was found to be affected by environmentally relevant cosolutes in experiments using cavity ring-down spectroscopy (CRDS) and electrospray ionization mass spectrometry (ESIMS) for the detection of gaseous and interfacial products, respectively. Iodine, I2(g), and iodine monoxide radical, IO(g), product yields were suppressed in

    Laser-induced fluorescence spectroscopy via excitation of the A2pi(3/2) <-- X2pi(3/2) (2,0) band at 445 nm was used to monitor IO in the presence of NO2 following its generation in the reactions O(3P) + CF3I and O(3P) + I2. Both photolysis of O3 (248 nm) and NO2 (351 nm) were used to initiate the production of IO. The rate coefficients for the thermolecular reaction IO + NO2 + M --> IONO2 + M were measured
    通过激发445 nm处的A2pi(3/2)<-X2pi(3/2)(2,0)谱带产生的激光诱导的荧光光谱用于监测IO在存在于反应O中后是否存在NO2的情况(3P)+ CF3I和O(3P)+ I2。O3(248 nm)和NO2(351 nm)的光解均用于引发IO的产生。在空气,氮气和氧气中,在P = 18-760 Torr范围内(涵盖典型的对流层条件),测量了热分子反应IO + NO2 + M-> IONO2 + M的速率系数地区。没有观察到k1对浴液气体身份的依赖性,通常,结果与最近的测定结果非常吻合。使用Troe展宽因子F(B)= 0.4,衰减参数k0(1)=(9.5 +/- 1.6)x 10(-31)cm6分子(-2)s(-1)和k(无穷大) (1)=(1.7 +/- 0。3)在294 K下测定了10(-11)cm3分子(-1)s(-1)。使用IO在高温下的时间分布来研究产物IONO2的
