Thrust was to elucidate simple elementary reactions and to unravel mechanism of complex/photochemical reactions. Molecular beams are used to study reactions between molecules or to monitor photodissociation events in a collision-free environment. Recent activities centered on reactions involving oxygen atoms with unsaturated hydrocarbons, endothermic substitution reactions, dependence of reactivity of excited atoms on alignment of excited orbitals, photochemical reactions of polyatomic, energy transfer, free radicals in combustion processes, infrared absorption spectra of carbonium ions and hydrated hydronium ions, and bond-selective photodissociation.
Activity in any theoretical area is usually stimulated by new experimental techniques and the resulting opportunity of measuring phenomena that were previously inaccessible. Such has been the case in the area under consideration he re beginning about fifteen years aga when the possibility of studying chemical reactions in crossed molecular beams captured the imagination of physical chemists, for one could imagine investigating chemical kinetics at the same level of molecular detail that had previously been possible only in spectroscopic investigations of molecular stucture. This created an interest among chemists in scattering theory, the molecular level description of a bimolecular collision process. Many other new and also powerful experimental techniques have evolved to supplement the molecular be am method, and the resulting wealth of new information about chemical dynamics has generated the present intense activity in molecular collision theory. During the early years when chemists were first becoming acquainted with scattering theory, it was mainly a matter of reading the physics literature because scattering experiments have long been the staple of that field. It was natural to apply the approximations and models that had been developed for nuclear and elementary particle physics, and although some of them were useful in describing molecular collision phenomena, many were not.
This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.
Rapid developments in the study of oxygen reaction chemistry occurred as it is succeeded in obtaining an O(1D) beam source and commenced investigating the dynamics of several important reactions of O(3P) and O(1D). In the reaction of O(3P) with C6H6 and C6D6, two competing channels, one producing a stabilized addition complex and the other forming radical products C6H50 + H has been identified. Studies of the effects of collision energy and of deuteration were used to clarify the reaction mechanism. The reaction of O(3P) with another aromatic hydrocarbon toluene, results in competition between two substitution channels, loss of H atom and loss of CH3. In contrast to the 0 + C6H6 reaction, no stabilized oxygen-toluene adduct was observed.
