    Spectroscopic parameters, electrode potentials, acid ionization constants, and electron exchange rates of the 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) radicals and ions
    摘要:
    The characteristics of the colorless ABTS2- ion [ABTS - 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonate)] and of the persistent, intensely-colored radical ABTS- have been examined since some reported values are in disagreement. The standard reduction potentials of ABTS-/ABTS2- and ABTS.-/HABTS- are 0.68 and 0.81 V vs NHE, respectively. A second wave in the CV is associated with ABTS.-/ABTS.-, E1/2 = 1/09 V. The pH dependence of E-degrees leads to pK(a)(HABTS-) = 2.2 +/- 0.3; a spectrophotometric pH titration gives 2.08 +/- 0.02 at mu = 1.0 M. The protonated radical HABTS' was not detected (pK(a) < 0), consistent with the higher acidity of the radical relative to its reduced precursor. The EPR spectrum of ABTS.- shows a multiline spectrum centered at g = 2.0036 +/- 0.0004 from the hyperfine coupling to two sets of two equivalent nitrogens as well as six aromatic hydrogens. Line broadening of the methyl and aromatic resonances of ABTS2- in the presence of the radical gives an electron exchange rate constant of (4 +/- 1) x 10(7) L mol-1 s-1 for ABTS2-/ABTS.- in neutral aqueous solution. In 1.0 M perchloric acid, Fe3+ oxidizes HABTS- (k = 1.30 x 10(2) L mol-1 s-1) and Fe2+ reduces ABTS- (k = 7.5 x 10(2)L mol-1 s-1). Although the equilibrium constant K = k(f)/k(r) for the reaction agrees with that predicted by the measured potentials, the individual rate constants are much lower than those one calculates from the Marcus cross-relation, which is typical for reactions of Fe(H2O)63+ and Fe(H2O)62+.

    The electron-transfer quenching of photo-excited [Ru(bpy)32+](bpy = 2,2-bipyridine) by [Mo(CN)8]4– and Euaq2+ gives large positive and negative activation volumes (ΔV‡+ 24.7 and –11.0 cm3 mol–1), respectively, whereas quenching by other quenchers having quenching rate constants of > 109 mol–1 dm3 s–1 has a negligibly small pressure effect regardless of the charge of quencher.

    iron(II) in 0.5 M HClO(4) proceeds by both outer-sphere (86%) and inner-sphere (14%) electron-transfer pathways. The second-order rate constant for the outer-sphere reaction is 1.3 x 10(6) M(-1) s(-1). The inner-sphere electron-transfer reaction takes place via the formation of FeClO(2)(2+) that is observed as an intermediate. The rate constant for the inner-sphere path (2.0 x 10(5) M(-1) s(-1)) is controlled

    studied theoretically using the Arrhenius theory. The introduction of an anharmonic Morse function as the interaction potential was found to lead to a simple expression connecting σ2 and log k1, which is in accordance with the experimental results. It is also found that k1 correlates not only with σ2 but also a third order cumulant in EXAFS, C3; the greater the k1 value, the greater the increase in C3 with

    measured in dependence of ligands and temperature. For the series of related reactions the isokinetic relationship holds. As the donor number of the ligands increases, the activation energy is decreased according to the increase in electronic coupling, over the wide range of 50 kJ mol−1. At the same time the activation entropy shifts to more negative values, due to increased steric crowding in the successor
    摘要在乙腈中,Fe(tmphen)2+还原了一系列铁-(III)溶剂化物FeL3 + 6(L = TMP,DMF,DEF(=二乙基甲酰胺),AA(=乙酰胺)和DMSO)。 3(tmphen = 3,4,7,8-四甲基-1,10-菲咯啉)通过形成可动力学检测的中间体进行。所有可用的证据表明其形式为L5Fe(乙腈)Fe(tmphen)5 + 3,其中乙腈的特征是菲咯啉和FeL3 + 5之间的桥梁,因为CN三键与菲咯啉络合物外围的π轨道相互作用,并且腈氮配位为FeL3 + 5。已经根据配体和温度测量了该中间体的分解速率常数,表示实际的电子转移速率。对于一系列相关反应,等动力学关系成立。随着配体的供体数增加,在50 kJ mol-1的宽范围内,活化能随电子耦合的增加而降低。同时,由于后继复合物中空间拥挤的增加,激活熵在-41到-286 JK-1 mol-1的极负值的更宽范围内移动到更多的负值。因
