This book was released on 2009 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: We constructed a novel spectroscopic system to study rotationally inelastic collisions involving truly thermal molecular ions at low temperatures. This system utilizes magnetic confinement to generate abundant concentrations of ions and time-resolved double resonance (pump-probe) techniques to study rotational energy transfer. With this system, we studied chemical and physical processes involving HCO+ and CO+ molecular ions in gas mixtures containing hydrogen and carbon monoxide. We measured the relaxation cross section for the J=2 state of HCO+ in collisions with normal hydrogen at temperatures around 40 K and 77 K. The cross sections at the lower temperature are slightly below those predicted by Langevin theory, while those at the higher temperature are in good agreement with this theory. This dissertation discusses the discrepancy of the acquired data with Langevin theory at lower temperatures. We also performed rotational energy level spectroscopic studies of the methyl formate and symmetric mono-deuterated methyl formate molecules. We developed a rho-axis method (RAM) analysis to accurately model the rotational-torsional spectrum for the ground torsional state. In this work, we report the first measurement and analysis of millimeter-wave (mmw) and submillimeter-wave (submmw) rotational-torsional transitions for mono-deuterated methyl formate. Additionally, we extended the spectral analysis of methyl formate to higher angular momentum and higher spectral frequencies than previously reported.

Available in PDF, EPUB and Kindle. Book excerpt: These seven lectures are intended to serve as an introduction for beginning graduate students to the spectra of small molecules. The author succeeds in illustrating the concepts by using language and metaphors that capture and elegantly convey simple insights into dynamics that lie beyond archival molecular constants. The lectures can simultaneously be viewed as a collection of interlocking special topics that have fascinated the author and his students over the years. Though neither a textbook nor a scholarly monograph, the book provides an illuminating perspective that will benefit students and researchers alike.

Download or read book Cold Trapped Molecular Ions written by Roth Bernhard and published by VDM Publishing. This book was released on 2008 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the current themes in quantum physics is the creation of cold ( 1 K) molecules to study molecule-molecule, molecule-atom, and molecule-radiation interactions under these novel low-temperature conditions. This book highlights the field of cold trapped molecular ions. In particular, the development of a novel, universal cooling method for charged particles, sympathetic cooling using laser-cooled atoms, together with the experimental and computational techniques required are extensively reviewed. The book also reviews first spectacular applications of the cold ion ensembles produced: the study of the properties of cold non-neutral plasmas, the study of ion-neutral chemical reactions and of photodissociation processes, and high-resolution rotational overtone spectroscopy of cold hydrogen molecular ions with unprecedented spectral resolution. The large potential of this field of research and its possible impact to other fields of physics, chemistry, and biology are highlighted. The book summarizes the main lines of research in cold trapped molecular ion physics, thus, making it useful as an introduction for advanced students and experienced researchers.

Available in PDF, EPUB and Kindle. Book excerpt: The workshop on "The structure of small molecules and ions" was held at the Neve-Han guest house, near Jerusalem, Israel on December 13 to 18 in mem ory of the late Professor Itzhak Plesser. Professor Plesser played a central role in the research done both at the Weizmann Institute and at Argonne National Laboratories on the "Coulomb explosion" method. His friends honored his memory by organizing a meeting in which subjects related to Plesser's interests would be discussed. Just a week be fore the conference started we were struck by another tragedy -the death of our graduate student Ms. Hana Kovner, who participated in many of the Coulomb explosion experiments at the Weizmann Institute. We would like to dedicate these proceedings to her memory as well. The goal of the workshop was to bring together chemists and physicists working on different aspects of the structural problems of small molecular en tities. The time seemed appropriate for discussing experimental and theoretical concepts, since in recent years new methods have been introduced, and a large amount of information has been accumulated on systems not studied before, like unstable molecules, ions, van der Waals molecules and clusters. The program of the workshop reflects, we believe, these new developments. The meeting was characterized by intensive discussions in which the weak nesses and strengths of new and of well established concepts were revealed. We hope that it measured up to the high standards Itzhak Plesser maintained all through his scientific life.
