Identification of Multiple Water–Iodide Species in Concentrated NaI Solutions Based on the Raman Bending Vibration of Water

29-Jan-2016 | Matthieu Besemer; Rob Bloemenkamp; Freek Ariese; Henk-Jan van Manen, Journal of Physical Chemistry A, 2016

The influence of aqueous electrolytes on the water bending vibration was studied with Raman spectroscopy. For all salts investigated (NaI, NaBr, NaCl, and NaSCN), we observed a nonlinear intensity increase of the water bending vibration with increasing concentration. Different lasers and a ...

Photoinduced Electron Transfer between Anionic Corrole and DNA

20-Jan-2016 | Li-Li Wang; Lei Zhang; Hui Wang; Yang Zhang; Jun-Teng Huang; He Zhu; Xiao Ying; Liang-Nian Ji; Hai-Yang Liu, Journal of Physical Chemistry A, 2016

The interaction between a water-soluble anionic Ga(III) corrole [Ga(tpfc)(SO3Na)2] and calf thymus DNA (ct-DNA) has been investigated by using femtosecond transient absorption spectroscopy. A significant broadening from 570 to 585 nm of positive absorption band of the blend of Ga(tpfc)(SO3Na)2 ...

Thermochemistry of Ruthenium Oxyhydroxide Species and Their Impact on Volatile Speciations in Severe Nuclear Accident Conditions

20-Jan-2016 | Faoulat Miradji; François Virot; Sidi Souvi; Laurent Cantrel; Florent Louis; Valérie Vallet, Journal of Physical Chemistry A, 2016

Literature thermodynamic data of ruthenium oxyhydroxides reveal large uncertainties in some of the standard enthalpies of formation, motivating the use of high-level relativistic correlated quantum chemical methods to reduce the level of discrepancies. Reaction energies leading to the formation ...

Hierarchy of the Collective Effects in Water Clusters

20-Jan-2016 | Imre Bakó; István Mayer, Journal of Physical Chemistry A, 2016

The Journal of Physical Chemistry A DOI: 10.1021/acs.jpca.5b10053

Raman Spectroscopic Studies of Clathrate Hydrate Formation in the Presence of Hydrophobized Particles

12-Jan-2016 | Huijuan Li; Paul Stanwix; Zachary Aman; Michael Johns; Eric May; Liguang Wang, Journal of Physical Chemistry A, 2016

In the present work, Raman spectroscopy was used to study the structure of water molecules in the vicinity of glass particles with different hydrophobicity, immersed in water and in tetrahydrofuran and cyclopentane hydrates. The glass particle surfaces were clean (hydrophilic), coated with ...

Source of Molecular Hydrogen in High-Temperature Water Radiolysis

07-Jan-2016 | Marcin Sterniczuk; David M. Bartels, Journal of Physical Chemistry A, 2016

Molecular hydrogen is a primary product of the interaction of low-LET (γ, β) radiation with water, and previous measurements have shown that its initial yield increases at elevated temperature. This has been the subject of controversy because more atomic H and (e–)aq free radicals escape ...

Aging Oxidation Reactions on Atmospheric Black Carbon by OH Radicals. A Theoretical Modeling Study

22-Dec-2015 | Laura Rojas; Alexander Peraza; Fernando Ruette, Journal of Physical Chemistry A, 2015

Aging processes of black carbon (BC) particles require knowledge of their chemical reactivities, which have impact on cloud condensation nuclei (CCN) activities, radiant properties and health problems related to air pollutions. In the present work, interactions between several OH radicals with BC ...

Trapped Hydronium Radical Produced by Ultraviolet Excitation of Substituted Aromatic Molecule

16-Dec-2015 | Federico J. Hernández; Marcela C. Capello; Ayumi Naito; Shun Manita; Kohei Tsukada; Mitsuhiko Miyazaki; Masaaki Fuji ..., Journal of Physical Chemistry A, 2015

The gas phase structure and excited state dynamics of o-aminophenol-H2O complex have been investigated using REMPI, IR-UV hole-burning spectroscopy, and pump–probe experiments with picoseconds laser pulses. The IR-UV spectroscopy indicates that the isomer responsible for the excitation spectrum ...

Hydrogen Isotope Exchange of Chlorinated Ethylenes in Aqueous Solution: Possibly a Termolecular Liquid Phase Reaction

14-Dec-2015 | Mario Gabričević; Gábor Lente; István Fábián, Journal of Physical Chemistry A, 2015

This work reports an experimental study of the hydrogen/deuterium exchange in the basic aqueous solutions of trichloroethylene, trans-1,2-dichloroethylene, and cis-1,2-dichloroethylene using 1H NMR as a monitoring method. 1,1-Dichlorethylene was also investigated but found not to exchange ...

Probing the Evaporation Dynamics of Ethanol/Gasoline Biofuel Blends Using Single Droplet Manipulation Techniques

14-Dec-2015 | Stella Corsetti; Rachael E. H. Miles; Craig McDonald; Yuri Belotti; Jonathan P. Reid; Johannes Kiefer; David McGloin, Journal of Physical Chemistry A, 2015

Using blends of bioethanol and gasoline as automotive fuel leads to a net decrease in the production of harmful emission compared to the use of pure fossil fuel. However, fuel droplet evaporation dynamics change depending on the mixing ratio. Here we use single particle manipulation techniques to ...
