This book was released on 1962 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the first step in making assignments of the low-frequency vibrations of para-substituted benzene compounds, complete vibrational assignments of several representative compounds have been started. While assignments have been made for many monosubstituted benzenes, there is need for a complete assignment of a monosubstituted benze with an electron-attracting substituent. To fill this need, an assignment of benzonitrile has been made. Attempts to prepare benzonitrile-d sub 5 were unsuccessful, but are being continued. To confirm the previous assignment of phenol, a sample of phenol-2,4,6-d sub 3 was prepared. A complete vibrational assignment of this molecule was made. Attempts to prepare phenol-d sub 5 are in progress. The assignments of p-cresol and deuterated p-cresols was carried almost to completion. Using the vibrational assignments mentioned above as a foundation, the low-frequency vibrations of 28 para-substituted benzene compounds were assigned as completely as possible. It was shown that certain of the lowfrequency vibrations are sensitive to the nature of the substituent. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This author's second volume introduces basic principles of interpreting infrared spectral data, teaching its readers to make sense of the data coming from an infrared spectrometer. Contents include spectra and diagnostic bands for the more common functional groups as well as chapters on polyester spectra and interpretation aids. Discussions include: Science of infrared interpretation Light and molecular vibrations How and why molecules absorb infrared radiation Peak heights, intensities, and widths Hydrocarbons, carbonyl groups, and molecules with C-N bonds Polymers and inorganic molecules The use of atlases, library searching, spectral subtraction, and the Internet in augmenting interpretation Each chapter presents an introduction to the nomenclature and structure of a specific functional group and proceeds with the important diagnostic bands for each group. Infrared Spectral Interpretation serves both novices and experienced practitioners in this field. The author maintains a website and blog with supplemental material. His training course schedule is also available online.

Download or read book Infrared Spectroscopy in Conservation Science written by Michele R. Derrick and published by Getty Publications. This book was released on 2000-03-16 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides practical information on the use of infrared (IR) spectroscopy for the analysis of materials found in cultural objects. Designed for scientists and students in the fields of archaeology, art conservation, microscopy, forensics, chemistry, and optics, the book discusses techniques for examining the microscopic amounts of complex, aged components in objects such as paintings, sculptures, and archaeological fragments. Chapters include the history of infrared spectroscopy, the basic parameters of infrared absorption theory, IR instrumentation, analysis methods, sample collection and preparation, and spectra interpretation. The authors cite several case studies, such as examinations of Chumash Indian paints and the Dead Sea Scrolls. The Institute’s Tools for Conservation series provides practical scientific procedures and methodologies for the practice of conservation. The series is specifically directed to conservation scientists, conservators, and technical experts in related fields.

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 Quantitative Spectroscopy Theory and Practice written by Brian C. Smith and published by Elsevier. This book was released on 2003-01-17 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the concentrations of molecules in samples has long been an important application of spectroscopy. In the last 20 years advances in algorithms, computers, instruments, and software have led to a growing interest in this field. These developments mean samples and analytes that were once considered intractable are increasingly yielding usable calibrations. The purpose of this book is to give readers, without an advanced math background, a thorough grounding in the theory and practice of modern quantitative spectroscopic analysis. The author has placed great emphasis on providing the reader with everything they need to know to obtain a fundamental understanding of quantitative spectroscopy.·Relevant theory is explained in an easy to understand, conversational style. ·Actual spectroscopic data and calibrations are used throughout the book to show how real world calibrations are achieved. ·The complexities of Factor Analysis (PCR/PLS) algorithms are explained in pictures and words, making them understandable for all. ·Written from a spectroscopic rather than a mathematical point of view.·Relevant theory is interspersed with practical discussions in order to make difficult concepts easier to comprehend·It is a comprehensive introduction for novices, and an excellent reference for experts.·Topics on spectroscopy are included to emphasize its importance in quantitative spectroscopy
