Book Description
This monograph is devoted to the basic aspects of the physics of highly ex cited (Rydberg) states of atom's. After almost twenty years, this remains a hot topic of modern atomic physics. Such studies are important for many areas of physics and its applications including spectroscopy, astrophysics and radio astronomy, physics of electronic and atomic collisions, kinetics and di agnostics of gases, and low- and high-temperature plasmas. Physical phenom ena in radiative, collisional, and spectral-line broadening processes involving Rydberg atoms and ions are primarily determined by the peculiar properties and exotic features of highly excited states. The growth of interest and research activity in the physics of Rydberg the last two decades was stimulated by an extremely rapid de atoms over velopment of high-resolution laser spectroscopy, methods of selective excita tion and detection of highly excited states, atomic-beam techniques as well as radio astronomy. This has facilitated significant progress in the differ ent directions of the physics of highly excited atoms being of fundamental and practical importance. In particular, evident advances were achieved in studies of the structure and spectra of highly excited atoms, their behavior in static electric and magnetic fields, interactions with electromagnetic ra diation, spectral-line broadening and the shift of Rydberg series, collisions with electrons, ions, atoms, and molecules, etc. The principle objective of the present book is to reflect the most important physical approaches and efficient theoretical techniques in the modem physics of highly excited atoms and ions.

Book Description
After the development of the tunable laser, experimental studies in Rydberg states of atoms and molecules grew at a remarkable rate. Fundamental questions were resolved, opening doors for more experimental activity and theoretical inquiry. In this comprehensive summary of knowledge of Rydberg states, which was originally published in 1983, Professors Stebbings and Dunning brought together a select collection of experimental and theoretical discussions. Composed of works by the acknowledged leaders in the field, this volume will be of value for anyone with an interest in molecular physics.

Book Description
Higher Excited States of Polyatomic Molecules, Volume II focuses on a higher level of activity in vacuum ultraviolet spectroscopy. This book explores the Rydberg states in atoms and molecules. Comprised of five chapters, this volume starts with an overview of the two-center unsaturated molecules that usually display sharp Rydberg transitions originating with the pi electrons. This book then discusses the unsaturated double bond that adds another dimension to the spectrum. Other chapters explore the optical spectrum of the amide group, which is the basic chromophoric unit in polypeptides. This text further discusses the all-electron calculations of the electronic structure of the amide group that is performed in Gaussian orbital basis sets. This book considers as well the prominent characteristic of Rydberg excitations in benzene. The final chapter deals with the biological molecules that are polyfunctional in general. Analytical chemists, photochemists, molecular spectroscopists, and researchers will find this book extremely useful.

Book Description
Higher Excited States of Polyatomic Molecules, Volume I focuses on the spectra in the vacuum-ultraviolet region between 50,000 and 100,000 cm-1. This book explores the higher excitations in molecules beyond 50,000 cm-1. Organized into three chapters, this volume starts with an overview of the excited-state properties of a molecule and the excited-state ionization potential. This book then proceeds with a discussion of the original classification of the properties as well as the types of excitations observed in the vacuum-ultraviolet. Other chapters discuss photoelectron spectroscopy, which is an independent, self-sustaining branch of molecular spectroscopy. This text examines as well the distinction between valence shell and Rydberg excitations. The final chapter deals with several topics, including the saturated molecules that are classified as having all valence electrons, the alkene absorption spectra, and the spectroscopic data on boron compounds. Analytical chemists, photochemists, molecular spectroscopists, and researchers will find this book extremely useful.

Book Description
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.

Book Description
As part of the Physics 2010 decadal survey project, the Department of Energy and the National Science Foundation requested that the National Research Council assess the opportunities, over roughly the next decade, in atomic, molecular, and optical (AMO) science and technology. In particular, the National Research Council was asked to cover the state of AMO science, emphasizing recent accomplishments and identifying new and compelling scientific questions. Controlling the Quantum World, discusses both the roles and challenges for AMO science in instrumentation; scientific research near absolute zero; development of extremely intense x-ray and laser sources; exploration and control of molecular processes; photonics at the nanoscale level; and development of quantum information technology. This book also offers an assessment of and recommendations about critical issues concerning maintaining U.S. leadership in AMO science and technology.
