Download or read book NMR Spectroscopy in Organic Chemistry written by B. I. Ionin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years high-resolution nuclear magnetic resonance spec troscopy has found very wide application in organie chemistry in structural and physicochemical investigations and. also in the study of the characteristics of organic compounds which are re lated to the distribution of the electron cloud in the molecules. The vigorous development of this method, which may really be re garded as an independent branch of science, is the result of ex tensive progress in NMR technology, the refinement of its theory, and the accumulation of large amounts of experimental material, which has been correlated by empiricallaws and principles. The literature directly concerned with the NMR method and its applica tion has now grown to such an extent that a complete review of it is practically impossible. Therefore the authors have limited themselves to an examination of only the most important, funda mental, and general investigations. The book consists of six chapters. In the first chapter we have attempted to present the fundamentals of the NMR method in such a way that the reader with little knowledge of the subject will be able to use the method in practical work for investigating simple compounds and solving simple problems. The three subsequent chapters give a deeper analysis of the method, while the last two chapters and the appendix illustrate the various applications of NMR spectroscopy in organic chemistry.

Download or read book Organic Structures from 2D NMR Spectra written by L. D. Field and published by John Wiley & Sons. This book was released on 2015-06-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. Over recent years, a number of powerful two-dimensional NMR techniques (e.g. HSQC, HMBC, TOCSY, COSY and NOESY) have been developed and these have vastly expanded the amount of structural information that can be obtained by NMR spectroscopy. Improvements in NMR instrumentation now mean that 2D NMR spectra are routinely (and sometimes automatically) acquired during the identification and characterisation of organic compounds. Organic Structures from 2D NMR Spectra is a carefully chosen set of more than 60 structural problems employing 2D-NMR spectroscopy. The problems are graded to develop and consolidate a student’s understanding of 2D NMR spectroscopy. There are many easy problems at the beginning of the collection, to build confidence and demonstrate the basic principles from which structural information can be extracted using 2D NMR. The accompanying text is very descriptive and focussed on explaining the underlying theory at the most appropriate level to sufficiently tackle the problems. Organic Structures from 2D NMR Spectra Is a graded series of about 60 problems in 2D NMR spectroscopy that assumes a basic knowledge of organic chemistry and a basic knowledge of one-dimensional NMR spectroscopy Incorporates the basic theory behind 2D NMR and those common 2D NMR experiments that have proved most useful in solving structural problems in organic chemistry Focuses on the most common 2D NMR techniques – including COSY, NOESY, HMBC, TOCSY, CH-Correlation and multiplicity-edited C-H Correlation. Incorporates several examples containing the heteronuclei 31P, 15N and 19F Organic Structures from 2D NMR Spectra is a logical follow-on from the highly successful “Organic Structures from Spectra” which is now in its fifth edition. The book will be invaluable for students of Chemistry, Pharmacy, Biochemistry and those taking courses in Organic Chemistry.

Download or read book Advances in Oxygen 17 NMR for Biological Structure Determination written by Eric George Keeler and published by . This book was released on 2017 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the structures of biological systems, such as, fibril-forming peptides and proteins, membrane proteins, and viruses, by solid-state nuclear magnetic resonance (NMR) spectroscopy has materialized as an important field due to the high-resolution details that the technique provides. While solid-state NMR studies have focused on the three prevalent spin I = 1/2 nuclei present in biomolecules, oxygen has largely been ignored as a probe of the structure of such systems. Described in this thesis are the results of studies to advance the use of solid-state 17O NMR spectroscopy for structure determination of biological molecules by utilizing the sensitivity of the electric field gradient (EFG) and chemical shift tensors of 17O. We demonstrated a distinct chemical shift range for bound water in crystalline amino acids and dipeptides and identified discordance between experimental and calculated EFG parameters. This difference was further studied via variable temperature 17O NMR experiments on barium chlorate monohydrate that demonstrated the effect of the librational motions of the bound water on the NMR measurable 17O quadrupolar coupling constant. A well resolved splitting in the 17O magic-angle spinning NMR spectrum was shown at the'rigid lattice limit of the bound water that was determined to be caused by the interaction between the 1H-1H dipole coupling and the 1H-17O dipole couplings. Further study of bound water environments is presented exhibiting the ability to resolve multiple unique bound water environments in a single system by high-resolution 17O NMR spectroscopy. We demonstrate the ability to utilize dynamic nuclear polarization (DNP) NMR to polarize multiple nuclei via an endogenous radical dopant that does not disrupt the native crystal structure. Efficient 17O labeling of a dipeptide is explored to enable the study of the dipeptide via 17O NMR. Utilizing one- and two-dimensional double resonance correlation spectroscopy, the interatomic correlations between oxygen and carbon, nitrogen, and hydrogen atoms were explored, exhibiting the ability of 17O NMR to determine structural characteristics of biomolecular solids. A study on the use of DNP NMR to study biosilica entrapped proteins is also presented as part of this thesis.

Book excerpt: In recent years, there has been a major expansion of high pressure research providing unique information about systems of interest to a wide range of scientific disciplines. Since nuclear magnetic resonance has been applied to a wide spec trum of problems in chemistry, physics and biochemistry, it is not surprising to find that high pressure NMR techniques have also had many applications in these fields of science. Clearly, the high information content of NMR experiments combined with high pressure provides a powerful tool in modern chem istry. It is the aim of this monograph, in the series on NMR Basic Principles and Progress, to illustrate the wide range of prob lems which can be successfully studied by high pressure NMR. Indeed, the various contributions in this volume discuss studies of interest to physics, chemical physics, biochemistry, and chemical reaction kinetics. In many different ways, this monograph demonstrates the power of modern experimental and theoretical techniques to investigate very complex systems. The first contribution, by D. Brinkman, deals with NMR and NQR studies of superionic conductors and high-Tc supercon ductors at high pressure. Pressure effects on phase transitions, detection of new phases, and pressure effects on diffusion and spin-lattice relaxation, represent a few of the topics discussed in this contribution of particular interest to solid state physics.
