Book Description
Significant progress has been made toward the ultimate goal of a comprehensive framework for systematic analysis of highly excited vibrational states of molecules. Traditional methods are predicated on assignment of eigenstates in terms of quantum numbers, such as the number of quanta in each normal mode, which are physically meaningful only in the low-energy, near-harmonic regime. What is needed is a new or at least much more general framework for spectra complicated by strong interactions among some or all of the degrees of freedom. We have been working toward such a framework through a systematic quest for understanding of the complex semiclassical dynamics underlying the quantum spectrum of the molecule. The main accomplishments achieved under this contract include: (1) determination of spectral patterns associated with phase space bifurcation structure and related spectral assignments with new quantum numbers; (2) assignment of spectra of polyatomics with three or more coupled degrees of freedom, following a bifurcation analysis of a chaotic Hamiltonian obtained from spectroscopic quantum fitting Hamiltonians; (3) the discovery of precessional modes in the bending spectra of acetylene, with assignment and related spectral patterns, following a bifurcation analysis of the spectral fitting Hamiltonian. jg.

Author: Laser Spectroscopy of Highly Vibrationally Excited Molecules
Author: Vladilen Stepanovich LetokhovPublisher: CRC Press
ISBN: 1000447855
Category : Science
Languages : en
Pages : 358
Book Description
Laser spectroscopy has been perfected over the last fifteen years to become a precise tool for the investigation of highly vibrationally excited molecules. Intense infrared laser radiation permits both the multiple-photon resonant excitation and the dissociation of polyatomic molecules. In this book, the latest results of some of the foremost Soviet researchers are published for the first time in the West. Laser Spectroscopy of Highly Vibrationally Excited Molecules contains a comprehensive study of both the experimental and theoretical aspects of the basic photophysical interactions that occur in these processes. The book first focuses on the nonlinear interaction between the resonant vibrational mode and the intense infrared field and then examines the nonlinear interaction between the vibrational modes themselves due to anharmonicity. These interrelated processes determine all the characteristics of polyatomic molecules in an infrared field. The book also discusses related phenomena such as spectra broadening, optical resonance, photon echoes, and dynamical chaos. It includes examples of multiple-photon resonant excitation such as the excitation of OsO4 by CO^O2 laser radiation, which is detected by the visible luminescence that results. This book will be of great interest to researchers and postgraduate students in infrared laser spectroscopy and the laser chemistry of molecules and applications of isotope separation.

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.
