Download or read book Interpretation of the Ultraviolet Spectra of Natural Products written by A. I. Scott and published by Elsevier. This book was released on 2013-10-22 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpretation of the Ultraviolet Spectra of Natural Products focuses on the ultraviolet spectrum of chromophores. The book first discusses single chromophores, including absorption due to electron lone pairs in saturated systems and absorption of olefins, alkynes, carbonyl compounds, and thiocarbonyl compounds. The text also takes a look at conjugated chromosomes, such as polyenes, enynes, and conjugated azomethines. The selection also evaluates C-aromatic compounds. Topics include benzenoid and hydrocarbons; phenols and their ethers; styrenes and stilbenes; aromatic carbonyl compounds; and nitro compounds. The text also discusses O- and S- heteroaromatic compounds and N-heteroaromatic compounds. The book highlights the applications of spectrophotometry to the analysis of natural products. Topics include formation of derivatives having absorbing chromophores; reactions leading to changes in absorption of added reagents; and analyses involving transformation to products suitable for spectrophotometry. The text is a good reference for readers wanting to explore chromophores.

Download or read book Higher Excited States of Polyatomic Molecules V3 written by Melvin Robin and published by Elsevier. This book was released on 2012-12-02 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Higher Excited States of Polyatomic Molecules, Volume III focuses on higher electronic excitations in polyatomic molecules, with emphasis on excitations beyond 50,000 cm-1. This book explores the various transitions on the basis of their orbital characteristics. Organized into 22 chapters, this volume begins with an overview of the relationships between spectra of different molecules and between the results of various types of spectroscopy. This book then discusses the higher excited states involving Rydberg excitation. Other chapters explore the higher excited states in all classes of biological, organic, and inorganic molecules. This text further discusses the progress in the area of higher excitations in polyatomic atoms and the technique of multiphoton ionization (MPI) spectroscopy that yields a remarkable amount of spectroscopic information applicable to the vacuum-ultraviolet region. The final chapter deals with the vacuum-ultraviolet spectroscopy of biological materials. Analytical chemists, photochemists, molecular spectroscopists, and researchers will find this book extremely useful.

Download or read book UV VIS Spectroscopy and Its Applications written by Heinz-Helmut Perkampus and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: UV-VIS spectroscopy is one of the oldest methods in molecular spectroscopy. The definitive formulation of the Bouguer-Lambert Beer law in 1852 created the basis for the quantitative evaluation of absorption measurements at an early date. This led firstly to colorimetry, then to photometry and finally to spectrophotometry. This evolution ran parallel with the development of detectors for measuring light intensities, i.e. from the human eye via the photo element and photocell, to the photomultiplier and from the photo graphic plate to the present silicon-diode detector both of which allow simultaneous measurement of the complete spectrum. With the development of quantum chemistry, increasing atten tion was paid to the correlation between light absorption and the structure of matter with the result that in recent decades a number of excellent discussions of the theory of electronic spectroscopy (UV-VIS and luminescence sp,~ctroscopy) have been published. Consequently, this extremely ivteresting aspect of molecular spec troscopy has dominated the teaching of the subject both in my own lectures and those of others. However, it is often overlooked that, in addition to the theory, applications of spectroscopic methods are of particular interest to scientists. For this reason, a lecture series about electronic spectroscopy given in the Institute for Physical Chemistry at the Heinrich-Heine-University in Dusseldorf was supplemented by one about "UV-VIS spectroscopy and its applications". This formed the basis of the present book.

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.

This book was released on 2021-03-27 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. - Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life - Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA - Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres
