A Reaction Accelerator: Mid-infrared Strong Field Dissociation Yields Mode-Selective Chemistry
The Journal of Physical Chemistry Letters, 2012Mode-selective chemistry has been a dream of chemists since the advent of the laser in the 1970s. Despite intense effort, this goal has remained elusive due to efficient energy randomization in polyatomic molecules. Using ab initio molecular dynamics calculations, we show that the interaction of molecules with intense, ultrashort mid-infrared laser ...

Band spectra and dissociation energies: A physical chemistry experiment
Journal of Chemical Education, 1962An experiment that has proved successful in introducing the spectroscopic determination of molecular energy levels and thermodynamic quantities is the analysis of the visible band spectrum of either iodine or bromine. In addition, this experiment introduces techniques now widely used in high temperature and astro-chemical studies.

Understanding Water Dissociation Physics through Controlled Oxide Surface Chemistry
ECS Meeting AbstractsBipolar membranes (BPMs) provide a platform for the interconversion between electric and chemical potential gradients and the precise control over local ion concentrations and fluxes, making BPMs attractive materials for many electrochemical processes.

The dissociation chemistry of permethylated guanosines as articulated by MS/MS
Tetrahedron Letters, 1993Abstract Permethylation of covalently modified guanosines is shown to be an effective means of increasing the abundance of structurally significant fragment ions when protonated base ions from nucleosides are subjected to collision-induced dissociation in MS/MS.

Use of hydration and dissociation chemistries with the electrolyte–NRTL model
AIChE Journal, 1999AbstractSound theoretical understanding and accurate mathematical representation of electrolyte solution nonideality were the subject of extensive research efforts for decades. It is demonstrated that these goals can be achieved by incorporation of hydration and partial dissociation chemistries with the semi‐empirical electrolyte NRTL model.

Wet-electron Enhanced Surface Dissociative Electron Attachment Chemistry of Halocarbons
2011Abstract : We investigated photocatalytic decomposition of organic compounds on rutile TiO2(110) single crystal surfaces in presence of near-UV light and O2 by two-photon photoemission spectroscopy. We found that the irradiation of water, methanol and ethanol induces deprotonation of the intact species to produce surface OH species.
