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.

Thermoacoustics and thermal dissociation of water

The Journal of the Acoustical Society of America, 2007
Near 2600 K, 10% of water molecules are thermally dissociated at atmospheric pressure, with a reaction time constant below 1 ms. Such temperatures can be reached with focused sunlight. To use this endothermic reaction for the production of hydrogen, the hydrogen must be separated from the oxygen at high temperature, because they would quickly recombine
