Available in PDF, EPUB and Kindle. Book excerpt: Molecular Rydberg states have many unusual properties, lending themselves to a diverse range of experimental applications. This book is designed to unravel the mysteries of molecular Rydberg states that lie beyond the scope of accepted spectroscopic theories. It is the first single-authored text to focus on the application of multi-channel quantum defect theory (MQDT) and ab initio theory to this special class of molecular systems, introducing readers to novel theoretical techniques. The scattering techniques of MQDT are examined, along with a unified description of bound states and fragmentation dynamics. Connections with established spectroscopic theory are also described. The book concludes with an account of the spherical tensor and density matrix theories required for the interpretation of multi-photon experiments. While the main text focuses on physical principles and experimental applications, appendices are used to handle advanced mathematical detail. This is a valuable resource for researchers in chemical, atomic and molecular physics.

This book was released on 1973 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis it is shown how Rayleigh-Schrddinger perturbation theory may be used to study intermolecular interactions and molecular Rydberg states.Chapter 1 is a general introduction to the nature of atomic and molecular Rydberg states.The perturbational approach that has been adopted here to deal with the Rydberg states of small molecules is described in Chapter 2.The results of calculations on the Rydberg states of the HgO and H2S molecules are presented and discussed in Chapter 3.In Chapter 4 intermolecular interactions and the problems that arise in the calculation of the intermolecular potentials, particularly in the region of the van der v.'aals minimum, are considered.It is shewn in Chapter 5 how the expression for the fir s t- order energy mu3t be altered when the zero-order approximation to the molecular wavefunction is not an exact eigenfunction of the zero-order hamiltonian. Then the He2 system is investigated to find how the first-order energy calculated using a particular approximate atomic wavefunction depends on the 'goodness' of that function.In Chapter 6 the potential energy curve for Ne2 is calculated in the range 4-3 a.u. The effect of allowing no penetration of the 1s core is also considered.The Appendix shows how the equations required for the Ne? calculation may be derived.iriuODinTiciiIn 1871 3toney[l] stated that the first, second and fourth.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains important contributions from top international scientists on the-state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. It consists of reviews and papers on ultrafast dynamics in molecular science.The coverage of topics highlights several important features of molecular science from the viewpoint of structure (space domain) and dynamics (time domain). First of all, the book presents the latest developments, such as experimental techniques for understanding ultrafast processes in gas, condensed and complex systems, including biological molecules, surfaces and nanostructures. At the same time it stresses the different ways to control the rates and pathways of reactive events in chemistry and biology. Particular emphasis is given to biological processes as an area where femtodynamics is becoming very useful for resolving the structural dynamics from techniques such as electron diffraction, and X-ray and IR spectroscopy. Finally, the latest developments in quantum control (in both theory and experiment) and the experimental pulse-shaping techniques are described.
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.

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.
Download or read book Excited States in Quantum Chemistry written by Cleanthes A. Nicolaides and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is undoubtedly true that much of the progress in the quant~m theory of matter is due to the remarkable success of the independent particle model (IPM)--especially in describing ground states. However, the accurate experimental results of the last 10 years or so, on a variety of spectroscopic phenomena and chemical processes which involve the Excited State, and the related failure of the IPM to reproduce accurately--in many cases, even qualitatively--the observed data, have sent to theorists a clear message: There is need to create and/or apply general and useful approaches to the many-electron problem of the excited state which go beyond the IPM, treat electron correlation and relativity and explain or predict all relevant physical or chemical information with consistent accuracy. This book contains articles devoted mainly to some of the most important new developments in Quantum Chemistry concerning the theoretical foundations and the computational implementation of many-body approaches to the quantitative and detailed under standing of the electronic excited states of atoms, molecules and solids. Furthermore, it contains experimental and pheno menological articles on Photoelectron and Auger spectroscopy, Lifetime measurements and Organic Photochemistry. In combination or individually, these articles constitute a good description of some current theoretical and experimental work on the electronic structure and spectroscopy of atoms, molecules, polymers, surfaces, metal oxides and amorphous solids.
