Dissociation of water by microwave radiation

Radiophysics and Quantum Electronics, 1994
The hydrogen-peroxide concentrations c(H2O2) in water irradiated by electromagnetic energy at frequencies of 2500 MHz and 10000 MHz are measured by means of chemiluminescence. It is concluded that water dissociation into H and OH groups is a part of the mechanism of microwave-radiation absorption.

Lifetimes of Excess Protons in Water Using a Dissociative Water Potential

The Journal of Physical Chemistry B, 2013
Molecular dynamics simulations using a dissociative water potential were applied to study transport of excess protons in water and determine the applicability of this potential to describe such behavior. While originally developed for gas-phase molecules and bulk liquid water, the potential is transferrable to nanoconfinement and interface scenarios ...

Structure-Dependent Dissociation of Water on Cobalt Oxide

The Journal of Physical Chemistry Letters, 2018
Understanding the correlation between structure and reactivity of oxide surfaces is vital for the rational design of catalytic materials. In this work, we demonstrate the exceptional degree of structure sensitivity of the water dissociation reaction for one of the most important materials in catalysis and electrocatalysis.

Dissociation of water on oxygen-covered Rh{111}

The Journal of Chemical Physics, 2009
The adsorption of water and coadsorption with oxygen on Rh{111} under ultrahigh vacuum conditions was studied using synchrotron-based photoemission and photoabsorption spectroscopy. Water adsorbs intact on the clean surface at temperatures below 154 K. Irradiation with x-rays, however, induces fast dissociation and the formation of a mixed OH+H2O layer

Dissociation constants of phenols in methanol–water mixtures

Journal of Chromatography A, 2000
A preferential solvation model that relates solute properties with solvent composition in binary mixtures has been applied to the dissociation pKa values of a set of 28 substituted phenols in methanol-water mixtures. The parameters of the model allow estimation of the pKa value of each phenol for any methanol-water composition.

Dissociative model of water clusters

The Journal of Chemical Physics, 1999
A model of water is introduced that dissociates into either ionic or covalent molecular fragments. The model is based on a semiempirical calculation embedded in a molecular mechanics approach. It contains electronic degrees of freedom that allow the calculation of partial charges that vary smoothly from the bound state to the dissociated states.

Increased Acid Dissociation at the Quartz/Water Interface

The Journal of Physical Chemistry Letters, 2018
As shown by a quite significant amount of literature, acids at the water surface tend to be "less" acid, meaning that their associated form is favored over the conjugated base. What happens at the solid/liquid interface? In the case of the silica/water interface, we show how the acidity of adsorbed molecules can instead increase.
