This book was released on 2007 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The near-infrared and visible band systems of the diatomic molecules CaH, FeO, ScS, MnH, RhO, and RhN have been studied utilizing high resolution spectroscopy. Most of these metal-containing species are free radicals and as such provide edifying spectra from which information regarding electronic structure can be gleaned. Directly accessible phenomena modeled by effective Hamiltonian methods are molecular rotation, spin-orbit, spin-spin, spin-rotation, lambda-doubling, magnetic hyperfine interactions, and electric quadrupole interactions. In the case of CaH a deperturbation analysis was performed and in the case of RhN isotopic substitution was analyzed. For CaH, FeO, RhO, and RhN, the application of an external static electric field i.e. Stark effect) allowed determination of permanent electric dipole moments of the ground and excited states probed. For CaH and MnH, the application of an external static magnetic field (i.e. Zeeman effect) allowed determination of effective g-factors. Parameters obtained from the data indirectly allow a description of the molecular orbitals involved, and were also compared to ab initio calculations. Due to the transient nature of these gas phase molecules, production was accomplished via laser ablation of a metal sample and introduction of an appropriate reagent gas. Subsequent supersonic expansion and molecular beam formation then allowed probing of the molecules by Laser Induced Fluorescence (LIF). High-resolution spectra were facilitated by a Continuous-Wave (CW) ring laser. Complementary to this, low or medium resolution spectra were obtained with a pulsed-dye laser (controlled via a homemade Visual Basic 6.0 computer program). Several previously unobserved band systems have been detected as part of a project involving survey scans of Rh metal plus various gas reagents including CH4, SF6, NH3, and D2.

Download or read book New Directions in Atomic Physics written by C.T. Whelan and published by Springer Science & Business Media. This book was released on 1999-09-30 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last few years have seen some remarkable advances in the understanding of atomic phenomena. It is now possible to isolate atomic systems in traps, measure in coincidence the fragments of collision processes, routinely produce, and study multicharged ions. One can look at bulk matter in such a way that the fundamental atomic character is clearly evident and work has begun to tease out the properties of anti matter. The papers in this book reflect many aspects of modem Atomic Physics. They correspond to the invited talks at a conference dedicated to the study of "New Directions in Atomic Physics," which took place in Magdalene College, Cambridge in July of 1998. The meeting was designed as a way of taking stock of what has been achieved and, it was hoped, as a means of stimulating new research in new areas, along new lines. Consequently, an effort was made to touch on as many directions as we could in the four days of the meeting. We included some talks which overviewed whole subfields, as well as quite a large number of research contributions. There is a unity to Physics and we tried to avoid any artificial division between theory and experiment. We had roughly the same number of talks from those who are primarily concerned with making measurements, and from those who spend their lives trying to develop the theory to describe the experiments.

Download or read book The Spectra and Dynamics of Diatomic Molecules written by Helene Lefebvre-Brion and published by Elsevier. This book was released on 2004-04-28 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for graduate students just beginning research, for theorists curious about what experimentalists actually can and do measure, and for experimentalists bewildered by theory. It is a guide for potential users of spectroscopic data, and uses language and concepts that bridge the frequency-and time-domain spectroscopic communities. Key topics, concepts, and techniques include: the assignment of simple spectra, basic experimental techniques, definition of Born-Oppenheimer and angular momentum basis sets and the associated spectroscopic energy level patterns (Hund's cases), construction of effective Hamiltonian matrices to represent both spectra and dynamics, terms neglected in the Born-Oppenheimer approximation (situations intermediate between Hund's cases, spectroscopic perturbations), nonlinear least squares fitting, calculation and interpretation of coupling terms, semi-classical (WKB) approximation, transition intensities and interference effects, direct photofragmentation (dissociation and ionization) and indirect photofragmentation (predissociation and autoionization) processes, visualization of intramolecular dynamics, quantum beats and wavepackets, treatment of decaying quasi-eigenstates using a complex Heff model, and concluding with some examples of polyatomic molecule dynamics. Students will discover that there is a fascinating world of cause-and-effect localized dynamics concealed beyond the reduction of spectra to archival molecular constants and the exact ab initio computation of molecular properties. Professional spectroscopists, kinetics, ab initio theorists will appreciate the practical, simplified-model, and rigorous theoretical approaches discussed in this book. - A fundamental reference for all spectra of small, gas-phase molecules - It is the most up-to-date and comprehensive book on the electronic spectroscopy and dynamics of diatomic molecules - The authors pioneered the development of many of the experimental methods, concepts, models, and computational schemes described in this book

Download or read book Quantum Mechanical Electronic Structure Calculations with Chemical Accuracy written by S. Langhoff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal focus of this volume is to illustrate the level of accuracy currently achievable by ab initio quantum chemical calculations. While new developments in theory are discussed to some extent, the major emphasis is on a comparison of calculated properties with experiment. This focus is similar to the one taken in a book, Comparison of Ab Initio Quantum Chemistry with Experiment for Small Molecules, edited by Rodney Bartlett (Reidel, 1984). However, the phenomenal improvement in both theoretical methods and computer architecture have made it possible to obtain accurate results for rather large molecular systems. This is perhaps best illustrated in this volume by the chapter entitled `Spectroscopy of Large Organic Molecules' by Bjorn Roos and coworkers. For example, the electronic spectra of the nucleic acid base monomer structures shown on the front cover have been obtained using a fully correlated ab initio study. For researchers, teachers and students in chemistry and physics.

Available in PDF, EPUB and Kindle. Book excerpt: This Festschrift is a collection of essays contributed by students, colleagues, and ad mirers to honor an eminent scholar on a special anniversary: Charles Hard Townes on the occasion of his 80th birthday, July 28, 1995. In 1964, Townes shared the Nobel Prize in physics with Alexander Mikhailovich Prokhorov and Nikolai Gen nadyevich Basov "for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle. " His contributions have covered a much wider area, however. His fruitful interests spanning several decades have included many scientific subjects, includ ing, microwave spectroscopy and astrophysics (other articles in this volume will expand further on this point). He has also contributed to public service, having served as the chairman of the Science and Technology Advisory Committee for NASA's Apollo program, and as a member and vice chairman of the President's Science Advisory Committee. As the enormous breadth of contributions from his students shows, he has educated scholars who are now in a wide range of fields. The contributions from his many admirers, among whom are nine fellow Nobel laureates, attest to his impact on many disciplines ranging from electrical engi neering to medicine. His influence extends even to theology, as is indicated by one essay. The broadly international character of this Festschrift reflects his deep belief in the international, universal nature of science.
