Download or read book NMR Band Handbook written by Herman Szymanski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development in recent years of NMR spectrometers capable of recording with a minimum of effort data that are both accurate and reproducible, a need has arisen for spectra catalogs and data books to aid the researcher. The ability to correlate a spectrum to a precalibrated chart accurately (to within 0. 02 ppm) has made chemical shift, along with the character of the spectral lines produced, an increasingly important tool in configurational analysis-a tool which this book is designed to complement. It is known that the chemical shift of a proton can be influenced by atoms as much as five or six carbons away, a fact of great importance to compound identification. The entries in this book, arranged according to proton environment, enable the researcher with a hypo thetical structure already proposed for his unknown quickly to locate examples of compounds having similar structures. An index of molecular formulas and a shift index, which should prove useful in hypothesizing alternate structures for the unknown and in checking out the hypotheses, have also been provided. The data collected represent some 4800 shifts from the spectra of about 1200 compounds that appear in the catalogs of Varian Associates, Sadtler Research Laboratories, and the American Petroleum Institute, whose cooperation is gratefully acknowledged. The alphanumerical code that is the basis of our presentation, and the explanation of its use, are borrowed intact from the NMR Spectra Catalog of Varian Associates, for whose permission to use this material we are especially grateful.
Download or read book Infrared Band Handbook written by Herman A. Szymanski and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Handbook includes all the data of the first edition and its supple ments and sufficient additional material to nearly double the total number of entries. It is hoped that enough entries are now given to represent most structural groups and environments. Infrared spectroscopy as a tool for the identification of compounds can be used in conjunction with other methods, such as NMR and UV spectros copy, or alone to quickly establish the presence or absence of particular structural groups. Computer search techniques can be applied to infrared data for the identification of unknowns, but the time required for the analysis will be substantial. These volumes will best serve those who wish to locate infrared data quickly and without recourse to instruments or related equipment. Typical applications in which the Handbook can best be utilized follow. 1. Searching a specific wavelength region for samples of compounds having absorption bands in that region, and relating this information to the compound under study. 2. Assigning vibrations for a compound by noting assignments for similar compounds. 3. Obtaining literature references. 4. Obtaining optimum sample conditions for determining the spectrum of a compound. 5. Identifying an unknown where data are not readily available. 6. Locating literature data on band positions, including references where only one band position is reported. 7. Enlarging present data files, including computer tapes. 8. Browsing through as many data as one wishes. Other mechanical or computer sources often yield too many data.

Download or read book Resinography written by Theodore Rochow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resinography is a strange new word to many people. Like all scientific terms, it is a word coined for a specific purpose: to indicate (in this case) that resins, polymers, and plastics write their own history on the molecular and other structural levels. The word indicates further that anyone trained and equipped to ask the right questions (by means of instruments and techniques) will be able to read that history. That person must have sufficient training and experience to interpret the answers, of course, and he or she needs to have the temperament of a detective. But in the end, as readers of this book will discover, one is able to identify the material, to determine its history of treatment, and to learn much about its possible field of usefulness. Obviously, the resinographer seeks to do the same thing with res ins, polymers, and plastics that the metallographer does with metals and their alloys. Often the investigative techniques and the instru ments, too, are similar, but sometimes they are decidedly different. Perhaps it would be best to say that resinography and metallographyl (and petrography as well) share a common origin, and that origin is deeply rooted in microscopy. The "grandfather" of all three "ographies" was Henry Clifton Sorby (1826-1908),2 who initiated 3 metallography and petrography, and was the first to report on the microstructure of a resin (amber, a natural fossil resin).

Book excerpt: The Porphyrin Handbook, Volume 16: Phthalocyanines: Spectroscopic and Electrochemical Characterization provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into five chapters, this volume begins with an overview of the photophysical properties of phthalocyanines that are important in relation to photosensitizers in photodynamic therapy, photoconductor, solar cells, and artificial photosynthesis. This text then describe how the data obtained from magnetic circular dichroism spectroscopy has provided the critical information required to describe the excited and ground state degeneracies of main group metallophthalocyanines complexes. Other chapters consider the electrocatalysis by electrodes modified with phthalocyanine sensors and complexes. This book discusses as well the properties of phthalocyanines and of their complexes. The final chapter deals with the experiments with organic pigment thin films. This book is a valuable resource for research scientists, engineers, and clinicians.
