Exploring the OH¿CO\H¿CO2 potential surface via dissociative photodetachment of „HOCO...À
Dissociative photodetachment ~DPD! of the molecular anion HOCO is used to probe the potential energy surface for the OH1CO→H1CO2 reaction. The HOCO anion, formed by electron impact on an expansion of CH41N2O1CO, is characterized for the first time in these experiments by photoelectron spectroscopy and photoelectron angular distribution measurements. Photodetachment of HOCO is found to produce H...
متن کاملDynamics on the HOCO potential energy surface studied by dissociative photodetachment of HOCO- and DOCO-.
An experimental study of the dissociative photodetachment (DPD) dynamics of HOCO(-) and DOCO(-) at a photon energy of 3.21 eV has been carried out to probe the potential energy surface of the HOCO free radical and the dynamics of the OH+CO-->H+CO(2) reaction. These photoelectron-photofragment coincidence experiments allow the identification of photodetachment processes leading to the production...
متن کاملFour-body reaction dynamics: complete correlated fragment measurement of the dissociative photodetachment dynamics of O(-)(8).
The four-body dissociative photodetachment (DPD) dynamics of O-8 were studied using photoelectron photofragment coincidence (PPC) spectroscopy. All four neutral photofragments were measured in coincidence with the photodetached electron, yielding a five-body kinematically complete experiment. Velocity and angular correlations for DPD of O(-)(8) are presented and compared to those for O(-)(6). T...

The dissociative photodetachment of O2 (H2O)n51 – 6 was studied at 388 and 258 nm using photoelectron–multiple-photofragment coincidence spectroscopy. Photoelectron spectra for the series indicate a significant change in the energetics of sequential solvation beyond the fourth water of hydration. Photoelectron–photofragment kinetic energy correlation spectra were also obtained for O2 (H2O)1 – 2...
متن کاملTransition state dynamics of the OH ¿ OH \ O ¿ H 2 O reaction studied by dissociative photodetachment of H
Photoelectron-photofragment coincidence ~PPC! spectroscopy has been used to study the dissociative photodetachment of H2O2 2 and D2O2 . The observed partitioning of photoelectron and photofragment translational energies provides information on the dynamics in the transition state region of the reaction between two hydroxyl radicals: OH1OH→O(P)1H2O. The data reveal vibrationally resolved product...
