Available in PDF, EPUB and Kindle. Book excerpt: AN UNPARALLELED ONE-STOP GUIDE TO FLUORINE NMR Guide to Fluorine NMR for Organic Chemists provides a unique single source on both fluorine NMR and the impact of fluorine substituents on proton and carbon NMR spectra. Helping working chemists overcome the challenges associated with the synthetic methodologies of fluorinated compounds, this guide enables the effective use of these increasingly popular spectroscopic techniques to accurately characterize compounds that contain fluorine. Following a thorough introduction of fluorinated compounds, chapters in the text cover: An overview of fluorine NMR The single fluorine substituent The CF2 group The trifluoromethyl group More heavily fluorinated compounds Compounds and substituents with fluorine directly bound to heteroatoms With unparalleled depth and completeness, the coverage ranges from those compounds containing only a few fluorinated substituents, typically employed in pharmaceutical and agricultural applications, to more heavily fluorinated compounds.

Download or read book High Resolution NMR Spectroscopy Understanding Molecules and their Electronic Structures written by and published by Newnes. This book was released on 2013-06-08 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The progress in nuclear magnetic resonance (NMR) spectroscopy that took place during the last several decades is observed in both experimental capabilities and theoretical approaches to study the spectral parameters. The scope of NMR spectroscopy for studying a large series of molecular problems has notably broadened. However, at the same time, it requires specialists to fully use its potentialities. This is a notorious problem and it is reflected in the current literature where this spectroscopy is typically only used in a routine way. Also, it is seldom used in several disciplines in which it could be a powerful tool to study many problems. The main aim of this book is to try to help reverse these trends.This book is divided in three parts dealing with 1) high-resolution NMR parameters; 2) methods for understanding high-resolution NMR parameters; and 3) some experimental aspects of high-resolution NMR parameters for studying molecular structures. Each part is divided into chapters written by different specialists who use different methodologies in their work. In turn, each chapter is divided into sections. Some features of the different sections are highlighted: it is expected that part of the readership will be interested only in the basic aspects of some chapters, while other readers will be interested in deepening their understanding of the subject dealt with in them. - Shows how NMR parameters are useful for structure assignment as well as to obtain insight on electronic structures - Emphasis on conceptual aspects - Contributions by specialists who use the discussed methodologies in their everyday work
Download or read book Fluorine Magnetic Resonance Imaging written by Ulrich Flogel and published by CRC Press. This book was released on 2016-10-26 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community owing to the unique properties of fluorinated materials and the 19F nucleus. Fluorine has an intrinsically sensitive nucleus for MRI. There is negligible endogenous 19F in the body and thus there is no background signal. Fluorine-containing compounds are ideal tracer labels for a wide variety of MRI applications. Moreover, the chemical shift and nuclear relaxation rate can be made responsive to physiology via creative molecular design. This book is an interdisciplinary compendium that details cutting-edge science and medical research in the emerging field of 19F MRI. Edited by Ulrich Flögel and Eric Ahrens, two prominent MRI researchers, this book will appeal to investigators involved in MRI, biomedicine, immunology, pharmacology, probe chemistry, and imaging physics.
Download or read book High Resolution NMR Spectroscopy written by Rubén H. Contreras and published by Elsevier Inc. Chapters. This book was released on 2013-06-08 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter describes briefly chemical shifts (or nuclear magnetic shielding constants) and indirect spin–spin coupling constants. They are well known as powerful tools for studying several molecular properties which are very important in different branches of the broad field of molecular sciences. The present description is oriented to an interdisciplinary audience and therefore it is expected that it can be followed for readers without strong backgrounds either in mathematics or physics. After a short revision of basic concepts, a qualitative method devised to extract information on electronic molecular structures is described. This aim is achieved employing this qualitative method for relating such parameters known in different series of compounds with several common chemical interactions. Since both types of NMR parameters present second-rank tensor properties, it is discussed how such property is affected in molecules measured in isotropic phase. Anybody with mathematical and physical background would answer immediately, “in isotropic phase is only observed one-third of the respective tensor trace.” However, in molecules that trace depends on the relative orientation of the Principal Axes System and bonds associated to the atom whose nuclear magnetic shielding is studied, or to the straight line connecting a pair of coupled nuclei. To describe these effects in this chapter is coined the expression “the geometric effect” to identify them. The same expression is also employed in . A list of exercises and appropriate references are included at the end of this chapter.

Available in PDF, EPUB and Kindle. Book excerpt: Several series of the diadducts of titanium tetrafluoride were studied with high-resolution fluorine-19 nuclear magnetic resonance (nmr) spectroscopy. These series consisted of fluorotitantate complexes of formula TiF4.2(donor) and TiF5.(donor)( -1), where donor represents an organic molecule (Lewis base) which coordinates through oxygen. The TiF4.2(donor) adducts included both TiF4.2D (D = donor) complexes, in which the donors are identical, and TiF4.D, D' complexes, in which D and D' represent different Lewis bases. Fluorine-19 chemical shifts and spin-spin coupling constants were determined for most of these fluorotitanate complexes. The temperature dependence of the TiF4.2D spectra was also studied. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The first part of the story explains how Virgils ancestors from Europe all arrived at that small region called Woodland, Indiana. Emphasis is on what was going on in that part of each ones world to cause them to migrate to this country and eventually to that spot in Indiana. Wars, religious intolerance, and decisions by the various kings or queens were the driving forces that caused so many to leave their homelands and look for better conditions. Life on a farm during the Great Depression and World War II is described in some detail. The emotional devastation upon learning of the deaths of two brothers in that war took a heavy toll on the Mochel Family. The second part deals with the many varied experiences of Virgil and Marian as they traveled their life-journey together, up to the present time.
