Available in PDF, EPUB and Kindle. Book excerpt: The structure and energetics of free radicals, ions, and clusters have been investigated by photoelectron photoion coincidence (PEPICO) and analyzed with the aid of ab initio molecular orbital and statistical theory (RRKM) calculations. The two major themes are the quantitative analysis of unimolecular reactions with no adjustable parameters, and the study of cluster ion dissociation processes. Molecules (or free radicals) were prepared in a molecular beam so that they are translationally and vibrationally cold. The translational temperature was calculated from the measured time of flight (TOF) peak width, while the vibrational temperature was determined from the shift in the dissociation onset. Free radicals are produced by pyrolysis in the nozzle, and subsequent cooling of the free radicals is demonstrated. Ion dissociation rates in the range from 104 to 107 sec−1 are measured from the asymmetric TOF distribution. This method was used to measure the dissociation rates of a number of cold and warm ions, among them HCl (DCl) loss from C2H5Cl (C2D5Cl), a reaction that proceeds via tunneling. The analysis of the butene ion dissociation provided information about the role of angular momentum in dissociation reactions. This dissociative ionization of ethylene clusters demonstrated that ethylene dimer ions rearranged to butene ions prior to dissociation. Finally, a new value for the t-butyl ion heat of formation, which corrects a 15 kJ/mol error in the previous value, was obtained from the 0 K breakdown diagram of t-butyl iodide.

Available in PDF, EPUB and Kindle. Book excerpt: The structure and energetics of free radicals, ions, and clusters have been investigated by photoelectron photoion coincidence (PEPICO) and analyzed with ab initio molecular orbital and statistical theory RRKM calculations. In these experiments, molecules are prepared in a molecular beam so that their internal as well as translational energies are cooled to near O K. The coincidence condition between energy analyzed electrons and their corresponding ions insures that the ions are energy selected. The primary experimental information includes ionization and fragment ion appearance energies, and the ion time of flight (TOF) distributions. The latter are obtained by using the energy selected electron as a start signal and the ion as the stop signal. These types of experiments allow us to measure the ion dissociation rates in the 104 to 107 sec −1 range. Such ions are commonly referred to a metastable ions. In addition, the TOF peak widths are related to the release of translational energy in the ion dissociation process. Perhaps the most important advance during the past year has been in the study of cluster photoionization. We have developed an experimental method for differentiating similar mass cluster ions based on the kinetic energy of the ions measured by TOF.

Available in PDF, EPUB and Kindle. Book excerpt: The photodissociation spectroscopy and dynamics of free radicals and ions is studied to characterize the dissociative electronic states in these species. To accomplish this, a special method of radical production, based on the photodetachment of the corresponding negative ion, has been combined with the technique of fast beam photofragment translational spectroscopy. The photofragment yield as a function of photon energy is obtained, mapping out the dissociative and predissociative electronic states. Branching ratios to various product channels, the translational energy distributions of the fragments, and bond dissociation energies are then determined at selected photon energies. The detailed picture of photodissociation dynamics is provided with the aid of ab initio calculations and a statistical model to interpret the observed data. Important reaction intermediates in combustion reactions have been studied: CCO, C2H5O, and linear C{sub n} (n = 4--6).

This book was released on 2003 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research during the last three years has focused on using negative ion photoelectron (PE) spectroscopy and zero electron kinetic energy (ZEKE) spectroscopy to probe the effects of clustering on the energetics, spectroscopy, and dynamics of ions and transition states, and to investigate the ground and excited electronic states of reactive free radicals. We have also developed a new spectroscopic method in which stimulated Raman pumping combined with PE spectroscopy is used to measure vibrational frequencies in negative ions. Results are summarized in more detail below.
