Direct Evaluation of the Hyperconjugative Interactions

Following the computational strategy proposed by Mulliken in 1939 (J. Chem. Phys. 7 (5), 339-352 (1939)) when the concept of hyperconjugation was coined, we evaluated the hyperconjugative stabilization energy in 1,1,1-trihaloethane using the block-localize ...

Enhanced Bromate Formation during Chlorination of Bromide-Containing Waters in the Presence of CuO: Catalytic Disproportionation of Hypobromous Acid

Urs von Gunten, Chao Liu

Bromate (BrO3–) in drinking water is traditionally seen as an ozonation byproduct from the oxidation of bromide (Br–), and its formation during chlorination is usually not significant. This study shows enhanced bromate formation during chlorination of brom ...

Iodate and Iodo-Trihalomethane Formation during Chlorination of Iodide-Containing Waters: Role of Bromide

Urs von Gunten

The kinetics of iodate formation is a critical factor in mitigation of the formation of potentially toxic and off flavor causing iodoorganic compounds during chlorination. This study demonstrates that the formation of bromine through the oxidation of bromi ...

Extraordinarily efficient conduction in a redox-active ionic liquid

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer, Guido Rothenberger, Verner Thorsmolle

Iodine added to iodide-based ionic liquids leads to extraordi- narily efficient charge transport, vastly exceeding that expect- ed for such viscous systems. Using terahertz time-domain spectroscopy, in conjunction with dc conductivity, diffusivity and visc ...

Kinetics and Mechanisms of N-Nitrosodimethylamine Formation upon Ozonation of N,N-Dimethylsulfamide-Containing Waters: Bromide Catalysis

Urs von Gunten

N,N-Dimethylsulfamide (DMS), a newly identified, ubiquitous degradation product of the fungicide tolylfluanide, has been shown to be a N-nitrosodimethylamine (NDMA) precursor during zonation. In this study, batch ozonation experiments in ultrapure buffered ...

Measurement of interlayer spin diffusion in the organic conductor kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]X, X = Cl, Br

László Forró, Richard Gaal, Bálint Náfrádi, Agnes Antal

In organic conductors the overlap integral between layers is small In-plane momentum scattering is rapid and transport perpendicular to the layers is expected to be blocked We present a high frequency conduction electron spin resonance (CESR) study in the ...

Reactivity of Alkyl Polyhalides toward Granular Iron: Development of QSARs and Reactivity Cross Correlations for Reductive Dehalogenation

Tamar Kohn

Attempts to develop quantitative structure-activity relationships (QSARs) for reductive dehalogenation have been hindered by the unavailability of high quality predictor variables, have included relatively few compounds, and on occasion have relied on data ...

Radical Stability Directs Electron Capture and Transfer Dissociation of Beta-Amino Acids in Peptides

Yury Tsybin, Hisham Ben Hamidane, Aleksey Vorobyev

We report on the characteristics of the radical-ion-driven dissociation of a diverse array of beta-amino acids incorporated into alpha-peptides, as probed by tandem electron-capture and electron-transfer dissociation (ECD/ETD) mass spectrometry. The report ...

Heterogeneous Chemistry of Cl2O and HOCl on Frozen Natural Sea Salt, Recrystallized Sea Salt, KCl and NaCl Solutions at 200 and 215 K

Michel Rossi, Pascal Pratte

The HOCl heterogeneous reaction on frozen natural (NSS) and recrystallized (RSS) sea salt KCl and NaCl solutions was studied using a low pressure flow reactor in order to measure the uptake coefficient gamma and products of reaction The HOCl sample used in ...
