This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rydberg states of molecules with high orbital angular momentum (l >/~ 3) are a unique class of electronic states. These high-l Rydberg states escape the rapid non-radiative decay by predissociation, which is typical of the intensively studied low-4 Rydberg states. Access to high-4 Rydberg states is challenging due to the [delta]l = ±1 transition propensity rule in combination with the short lifetimes of the optically accessible, low- Rydberg states. To address these dual challenges, we implement optical-millimeter-wave stimulated Raman adiabatic passage (optical-mmW STIRAP), which enables efficient population transfer from a low-lying electronic state to a high-l Rydberg state without directly populating a lossy, low-e Rydberg state. Our demonstration of optical-mmW STIRAP on an atomic system includes examination of the experimental and theoretical details of every step of this coherent process and demonstrates its promise for molecular applications. We explore the physics of the Rydberg electron -ion-core system through investigation of the spectroscopy and dynamics of high-l Rydberg states of NO. We populate ng Rydberg states of NO by a three-color triple-resonance excitation scheme and probe Rydberg-Rydberg transitions by chirped-pulse millimeter-wave (CPmmW) spectroscopy. The precision of the experimental data obtained and the breadth of the state space examined by CPmmW spectroscopy provides challenges to the existing theory of the structure of high-l Rydberg states. We apply a long-range electrostatic model to disentangle and describe the physical mechanisms that contribute to the autoionization dynamics of NO Rydberg states. Our model accounts for the decay rates of vibrationally excited ng Rydberg states. We explain the previously measured NO+ ion rotational state population distributions produced by autoionization of NO nf states and propose methods to generate single quantum state-selected NO+ ions by selective population of specific ng Rydberg states.

This book was released on 2006-04-11 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to offer a balanced overview of molecular Rydberg spectroscopy as it has developed over recent decades. Recent evolution has split Rydberg spectroscopy into two apparently distinct fields: the one concerns the low (n=3-5) Rydberg states, the other the very high (typically EMn/EM”150) Rydberg states. The former is aimed at spectral levels where Rydberg, valence-shell, and intermediate-type states interact, with a variety of photochemical consequences. The latter considers states extremely close to the ionization limit, from whereionization is possible with a very slight amount of additional energy. Recently developed techniques make it possible to produce ions in well-defined electronic, vibrational and rotational states, including states resulting from spin-orbit or Jahn-Teller splitting. It is then possible to study the structure and reactions of such state-selected ions as well as those of the corresponding neutral molecules. These techniques amount to badly needed high resolution photoelectron spectroscopy.
Download or read book Molecular Rydberg Dynamics written by M. S. Child and published by World Scientific Publishing Company. This book was released on 1997 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of molecular Rydberg states is a rapidly growing interdisciplinary field. This valuable report, constituting the proceedings of a Royal Society Discussion reflects the state of the present theoretical knowledge, and includes an introductory chapter for the non-specialist. e material is organised to bring out the wealth of observable effects. Some states commonly lead to competitive predissociation and autoionization, with relevance to atmospheric and astrophysical processes. Others, with higher angular momenta, have much longer lifetimes and high electronic degeneracies, which on one hand pose subtle problems for experimental interpretation, and on the other act as reservoirs for a class of remarkably stable so-called ZEKE states. New experiments to classify the formation mechanism of such states, and to exploit their properties, are described. The interplay between "quantum defect" and "ab initio" aspects of the theory is also underlined.

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 Frontiers of Molecular Spectroscopy written by Jaan Laane and published by Elsevier. This book was released on 2011-08-11 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of what we know about atoms, molecules, and the nature of matter has been obtained using spectroscopy over the last one hundred years or so. In this book we have collected together twenty chapters by eminent scientists from around the world to describe their work at the cutting edge of molecular spectroscopy. These chapters describe new methodology and applications, instrumental developments, and theory which is taking spectroscopy into new frontiers. The range of topics is broad. Lasers are utilized in much of the research, but their applications range from sub-femtosecond spectroscopy to the study of viruses and also to the investigation of art and archeological artifacts. Three chapters discuss work on biological systems and three others represent laser physics. The recent advances in cavity ringdown spectroscopy (CRDS), surface enhanced Raman spectroscopy (SERS), two-dimensional correlation spectroscopy (2D-COS), and microwave techniques are all covered. Chapters on electronic excited states, molecular dynamics, symmetry applications, and neutron scattering are also included and demonstrate the wide utility of spectroscopic techniques. Provides comprehensive coverage of present spectroscopic investigations Features 20 chapters written by leading researchers in the field Covers the important role of molecular spectroscopy in research concerned with chemistry, physics, and biology
