Book excerpt: Excited States, Volume 3 deals with excited states and covers topics ranging from two-photon molecular spectroscopy in liquids and gases to time evolution of excited molecular states. Product energy distributions in the dissociation of polyatomic molecules are also discussed, along with the mechanism of optical nuclear polarization in molecular crystals and vibronic interactions and luminescence in aromatic molecules with non-bonding electrons. Comprised of five chapters, this volume begins with a didactic treatment of the theory of simultaneous two-photon absorption spectroscopy from the point of view concerned primarily with molecular gases and liquids. The basic theoretical quantity is shown to be an absorption tensor, as contrasted with the absorption vector of one-photon spectroscopy. The next chapter considers the time evolution of a molecular system interacting with a photon wave packet. The theory is applied to handle photon scattering from several physical models for molecular level structure in excited electronic states of polyatomic molecules. The remaining chapters explore various polyatomic decomposition processes and the basic features governing the internal energy distribution of the fragments; optical nuclear polarization in molecular crystals and vibronic interactions; and luminescence in aromatic molecules with non-bonding electrons. This book should be of interest to chemists and molecular physicists.

Book excerpt: Excited States, Volume 2 is a collection of papers that deals with molecules in the excited states. The book describes the geometries of molecules in the excited electronic states. One paper describes the geometries of a diatomic molecule and of polyatomic molecules; it also discusses the determination of the many excited state geometries of molecules with two, three, or four atoms by techniques similar to diatomic spectroscopy. Another paper introduces an ordered theory related to excitons in pure and mixed molecular crystals. This paper also presents some experimental data such as those involving pure and neat crystals, very dilute isotopic mixed crystals, and medium dilute isotopic mixed crystals. The book also discusses the dynamics of primary photochemical processes including the classical theory of unimolecular reactions, the quantum theory of molecular reactions, and the theory of "nonchemical" radiationless processes. One paper also reviews the electron donor-acceptor complexes in their excited states. This book is suitable for nuclear physicists and researchers whose work involves molecular chemistry and solid state physics.

This book was released on 2012-06-13 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a breakthrough in the understanding of the large number of spectral lines in diamond. Data on more than 2000 lines and bands are presented in 200 tables, including many unpublished results. With a novel organization scheme, the search for a specific line is greatly simplified as a benefit for researchers and students. In order to meet the interest in the understanding of the spectra, structure assignments for 80 % of the lines are given, of which 15 % only were published before. The majority of the structures for the 300 centers is explained in most cases for the first time. A key instrument in the interpretation is the analysis by donor-acceptor pair transitions. In a special chapter 95 such centers are listed and discussed, of which only two have been published before, the first one by the present author in 1994.

Download or read book Spectroscopic Methods in Food Analysis written by Adriana S. Franca and published by CRC Press. This book was released on 2017-12-14 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the inherent complexity of food products, most instrumental techniques employed for quality and authenticity evaluation (e.g., chromatographic methods) are time demanding, expensive, and involve a considerable amount of manual labor. Therefore, there has been an increasing interest in simpler, faster, and reliable analytical methods for assessing food quality attributes. Spectroscopic Methods in Food Analysis presents the basic concepts of spectroscopic methods, together with a discussion on the most important applications in food analysis. The determination of product quality and authenticity and the detection of adulteration are major issues in the food industry, causing concern among consumers and special attention among food manufacturers. As such, this book explains why spectroscopic methods have been extensively employed to the analysis of food products as they often require minimal or no sample preparation, provide rapid and on-line analysis, and have the potential to run multiple tests on a single sample (i.e., non-destructive). This book consists of concepts related to food quality and authenticity, that are quite broad, given the different demands of the manufacturer, the consumer, the surveillance and the legislative bodies that ultimately provide healthy and safe products.

Download or read book Selected Papers of Robert S Mulliken written by Robert S. Mulliken and published by University of Chicago Press. This book was released on 1975-08 with total page 1180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together in one volume the most important papers of Robert S. Mulliken, who was awarded the 1966 Nobel Prize in chemistry for his seminal work on chemical bonds and the electronic structures of molecules. The papers collected here range from suggestive to closely detailed analyses of various topics in the theory of spectra and electronic structure of diatomic and polyatomic molecules. Professor Mulliken has written introductory commentaries on each of the volume's seven parts. Included in the volume are essays of general as well as scientific interest; they are grouped under thematic headings. Part I contains those papers which are of historical significance. An autobiographical piece by Dr. Mulliken offers a glimpse of the many famous people whom he has known. Also reprinted is the text of his Nobel Prize acceptance speech. At the end is a list of his students and other co-workers, and a complete bibliography of his papers. Part II includes Mulliken's work on band spectra and chemistry as well as his research on the assignment of quantum numbers for electrons in molecules. Part III surveys the author's early work on the bonding power of electrons and the method of molecular orbitals. Included is a discussion of the structure and spectra of a number of important types of molecules. The papers in part IV focus on the intensities of electronic transitions in molecular spectra. This incorporates Mulliken's work on charge transfer and the halogen molecule spectra. The problems addressed in part V center on the spectra and structure of polyatomic molecules. Reprinted here is a report which Mulliken prepared on notation for polyatomic molecules. Part VI is devoted to the problem of hyperconjugation. These papers develop and apply the concept of hyperconjugation and explore its relation to the concept of conjugation. The last part offers some of the most important papers from the author's postwar publications. The central focus is on molecular orbital theory, the area in which Mulliken's Nobel-winning discoveries were made.
