Book Description
"How does a photon get into an atom?" This question - fundamental to quantum mechanics - puzzled leading scientists such as Schrödinger and Heisenberg and is still asked by students. James D. Macomber's book was the first to provide a didactic and unified approach to the answer, which has now been updated by way of recent experimental results and modern theoretical interpretations written by leading scientists. It provides an understanding for similarities among the spectroscopic methods available and is stimulating to read, reflecting the excitement of scientific research.

Book Description
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

Book Description
The potential of degenerate-four wave mixing (DFWM) spectroscopy for the analysis of molecular species in high-pressure, high-temperature environments has been explored theoretically and experimentally. In addition, the reliability of DFWM has been assessed by comparing to laser induced fluorescence (LIF) measurements under the same experimental conditions. The results of these studies suggest that DFWM can provide quantitative information regarding trace molecular species in environments in which collisions and source emission hinder analysis by other means. DFWM has been used to detect the CH radical in an atmospheric-pressure oxyacetylene flame via the (0,0) and (1,1) bands of the A2 delta-X2 Pi system. The CH radical is a minor flame species and is important for understanding the primary reaction zone of many combustion environments. We have observed CH radicals with comparable sensitivity by both DFWM and LIF. From these measurements, we estimate a DFWM detection limit of 4 x 10(exp 11) molecules/ cu cm (4 x 10(exp 9) molecules/cu cm per quantum-state) for CH at atmospheric pressure. Vibrational temperatures and concentration profiles of CH obtained by both techniques are in good agreement.

Book Description
This book has been compiled to give specialists, in areas that could be helped by tunneling spectroscopy, a rounded and relatively painless intro duction to the field. Why relatively painless? Because this book is filled with figures-A quick glance through these figures can give one a good idea of the types of systems that can be studied and the quality of results that can be obtained. To date, it has been somewhat difficult to learn about tunneling spectroscopy, as papers in this field have appeared in a diversity of scientific journals: for example. The Journal of Adhesion, J(}urnal (}f Catalysis, Surface and Interface Analysis, Science, Journal of the American Chemical Society, Physical Review-over 45 different ones in all, plus numerous conference proceedings. This diversity is, however, undoubtedly healthy. It indicates that the findings of tunneling spectroscopy are of interest and potential benefit to a wide audience. This book can help people who have seen a few papers or heard a talk on tunneling spectroscopy and want to learn more about what it can do for their field. Tunneling spectroscopy is presently in a transitional state. Its experi mental methods and theoretical basis have been reasonably well developed. Its continued vitality will depend on the success of its applications. Crucial to that success, as pointed out by Ward Plummer, is the adoption of tunneling spectroscopy by specialists in the areas of application.
