Stereochemical Analysis of Alicyclic Compounds by C-13 NMR Spectroscopy
Author: J. A. WhitesellPublisher: Springer Science & Business Media
ISBN: 9400931611
Category : Science
Languages : en
Pages : 213
Book Description
Through numerous conversations with other synthetic chemists it became apparent that the great power of carbon nuclear magnetic resonance was being significantly underutilized. In our own work we have found that 13C spectroscopy is a more powerful tool than IH NMR spectroscopy, especially for probing subtle stereochemical questions in complicated systems. This is especially true in five membered ring compounds where IH NMR is at a particular disadvantage. The two techniques can be used independently to solve the same question-that of stereochemistry - but they do so in different ways. Advantage can be taken in IH NMR of a relatively consistent relationship between stereochemical orientation and coupling constants between vicinal protons, while in 13C NMR it is the correlation between spatial relationships of non-hydrogen, y substituents and their effect on chemical shift that can be used to assign stereochemistry. It was also clear that the use of 13C NMR required a different approach to problem solving than that typically used with IH NMR. While the latter technique could be employed with a very general approach (e.g., the Karplus equation), 13C NMR would, at least for the immediate future, require a relatively extensive set of model systems from which the consequences of stereochemical changes could be derived for any given carbon framework.
Modern Methods of Polymer Characterization
Author: Howard G. BarthPublisher: John Wiley & Sons
ISBN: 9780471828143
Category : Science
Languages : en
Pages : 582
Book Description
Presents the methods used for characterization of polymers. In addition to theory and basic principles, the instrumentation and apparatus necessary for methods used to study the kinetic and thermodynamic interactions of a polymer with its environment are covered in detail. Some of the methods examined include polymer separations and characterization by size exclusion and high performance chromatography, inverse gas chromatography, osmometry, viscometry, ultracentrifugation, light scattering and spectroscopy.

Topics in Stereochemistry
Author: Ernest L. ElielPublisher: John Wiley & Sons
ISBN: 0470147474
Category : Science
Languages : en
Pages : 354
Book Description
This seminal series, first edited by Ernest Eliel, responsible for some of the major advances in stereochemistry and the winner of the ACS Priestley Medal in 1996, provides coverage of the major developments of the field of stereochemistry. The scope of this series is broadly defined to encompass all fields of chemical and biological sciences that are founded on molecular and supramolecular interactions. Insofar as chemical, physical, and biological properties are determined by molecular shape and structure, the importance of stereochemistry is fundamental to and consequential for all natural sciences. Topics in Stereochemistry serves as a multidisciplinary series that enriches all of chemistry. Aimed at advanced students, university professors and teachers as well as researchers in pharmaceutical, agricultural, biotechnological, polymer, materials, and fine chemical industries, Topics in Stereochemistry publishes definitive and scholarly reviews in stereochemistry and has long been recognized as the gold standard reference work in this field. Covering the effect of chirality on all aspects of molecular interaction from the fundamental physical chemical properties of molecules and their molecular physics to the application of chirality in new areas such as its applications in materials science, Topics in Stereochemistry explores a wide variety of properties, both physical and chemical of isomers with a view to their applications in a number of disciplines from biochemistry to materials science.

A Complete Introduction to Modern NMR Spectroscopy
Author: Roger S. MacomberPublisher: John Wiley & Sons
ISBN: 0471157368
Category : Science
Languages : en
Pages : 406
Book Description
Clear, accessible coverage of modern NMR spectroscopy-for students and professionals in many fields of science Nuclear magnetic resonance (NMR) spectroscopy has made quantum leaps in the last decade, becoming a staple tool in such divergent fields as chemistry, physics, materials science, biology, and medicine. That is why it is essential that scientists working in these areas be fully conversant with current NMR theory and practice. This down-to-basics text offers a comprehensive, up-to-date treatment of the fundamentals of NMR spectroscopy. Using a straightforward approach that develops all concepts from a rudimentary level without using heavy mathematics, it gives readers the knowledge they need to solve any molecular structure problem from a complete set of NMR data. Topics are illustrated throughout with hundreds of figures and actual spectra. Chapter-end summaries and review problems with answers are included to help reinforce and test understanding of key material. From NMR studies of biologically important molecules to magnetic resonance imaging, this book serves as an excellent all-around primer on NMR spectroscopic analysis.
Practical Organic Synthesis
Author: Reinhart KeesePublisher: John Wiley & Sons
ISBN: 0470029668
Category : Science
Languages : en
Pages : 209
Book Description
Success in an experimental science such as chemistry depends on good laboratory practice, a knowledge of basic techniques, and the intelligent and careful handling of chemicals. Practical Organic Synthesis is a concise, useful guide to good laboratory practice in the organic chemistry lab with hints and tips on successful organic synthesis. Topics covered include: safety in the laboratory environmentally responsible handling of chemicals and solvents crystallisation distillation chromatographic methods extraction and work-up structure determination by spectroscopic methods searching the chemical literature laboratory notebooks writing a report hints on the synthesis of organic compounds disposal and destruction of dangerous materials drying and purifying solvents Practical Organic Synthesis is based on a successful course in basic organic chemistry laboratory practice which has run for several years at the ETH, Zurich and the University of Berne, and its course book Grundoperationen, now in its sixth edition. Condensing over 30 years of the authors’ organic laboratory teaching experience into one easy-to-read volume, Practical Organic Synthesis is an essential guide for those new to the organic chemistry laboratory, and a handy benchtop guide for practising organic chemists.
