Dissociation Mechanism of Acetic Acid in Water

Journal of the American Chemical Society, 2006
The reaction mechanism for acetic acid dissociation in aqueous solution has been investigated by combining the metadynamics method with transition path sampling (TPS). By using collective variables that describe not only the deprotonation of the acid but also the solvation state of the hydronium ion and its distance from the acetate, a reactive ...

Collision-Induced Dissociation of Water into Ions

The Journal of Physical Chemistry B, 2005
A modification of the central force model (CFM) that describes the dissociation of water molecules into OH- and H+ ions is proposed for molecular dynamics simulations of energetic particle bombardment of water ice. The model keeps all the properties of the CFM but permits charge exchange between oxygen and hydrogen atoms when the water molecule starts ...

Ultrafast Molecular Dissociation of Water in Ice

Physical Review Letters, 2004
Using x-ray emission and photoemission spectroscopies to measure the occupied valence levels in a thin crystalline ice film, we resolve the ionization-induced dissociation of water in ice on a femtosecond time scale. Isotope substitution confirms proton transfer during the core-hole lifetime in spite of the nonresonant excitation.

A direct measurement of the dissociation energy of water

The Journal of Chemical Physics, 2006
We have performed a direct measurement of one of the most fundamental thermochemical values: the O-H bond energy in water. Using a triple-resonance laser excitation scheme, we excite the molecule through a series of vibrational overtone transitions to access directly the onset of the dissociative continuum.

Concentration polarization and water dissociation in ion-exchange membrane electrodialysis. Mechanism of water dissociation

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1986
A relationship between the current density i and the current efficiency η of H+ and OH– ions generated by dissociation of water above the limiting current density in ion-exchange membrane electrodialysis has been proposed. Generation rates of H+ and OH– ions in the dissociation of water, H2O [graphic omitted] H++ OH– are given as the difference between
