Organic Structure Determination Using 2-D NMR Spectroscopy: A Problem-Based Approach de Jeffrey H. Simpson

Organic Structure Determination Using 2-D NMR Spectroscopy: A Problem-Based Approach

Autor Jeffrey H. Simpson
en Limba Engleză Paperback – 15 feb 2012

Credem că a doua ediție a lucrării Organic Structure Determination Using 2-D NMR Spectroscopy reprezintă un instrument metodologic esențial pentru cursul de chimie analitică la nivel universitar. Structura materialului este organizată riguros în două părți distincte: prima secțiune pune bazele teoretice și instrumentale (colectarea datelor, deplasări chimice, efecte de legătură și spațiale), în timp ce a doua parte este dedicată exclusiv aplicării practice prin rezolvarea de probleme. Această progresie logică asigură tranziția de la înțelegerea fenomenului fizic la expertiza tehnică necesară în laborator.

Ne-a atras atenția abordarea bazată pe probleme (problem-based approach), care transformă cititorul dintr-un observator pasiv într-un analist. Autorul, Jeffrey H. Simpson, continuă direcția începută în lucrarea sa anterioară, NMR Case Studies, unde punea accent pe fluxul logic al atribuirii spectrelor în cazul moleculelor complexe. În volumul de față, Jeffrey H. Simpson extinde acest concept, oferind strategii clare pentru deducerea structurilor organice necunoscute, susținute de un compendiu impresionant de 60 de probleme cu grade diferite de dificultate.

Putem afirma că acest titlu reprezintă o alternativă solidă la Organic Structures from Spectra de A. M. Magill pentru cursurile de determinare a structurilor, cu avantajul unei specializări stricte pe spectroscopia RMN bidimensională și al resurselor digitale incluse. Spre deosebire de manualele generale de spectroscopie, această ediție rafinează metodologiile de procesare și interpretare a datelor brute, fiind calibrată pentru nevoile actuale ale studenților și cercetătorilor care necesită o precizie înaltă în identificarea moleculară.

Descriere scurtă

Organic Structure Determination Using 2-D NMR Spectroscopy: A Problem-Based Approach, Second Edition, is a primary text for a course in two-dimensional (2-D) nuclear magnetic resonance (NMR) techniques, with the goal to learn to identify organic molecular structure. It presents strategies for assigning resonances to known structures and for deducing structures of unknown organic molecules based on their NMR spectra.
The book begins with a discussion of the NMR technique, while subsequent chapters cover instrumental considerations; data collection, processing, and plotting; chemical shifts; symmetry and topicity; through-bond effects; and through-space effects. The book also covers molecular dynamics; strategies for assigning resonances to atoms within a molecule; strategies for elucidating unknown molecular structures; simple and complex assignment problems; and simple and complex unknown problems. Each chapter includes problems that will enable readers to test their understanding of the material discussed. The book contains 30 known and 30 unknown structure determination problems. It also features a supporting website from which instructors can download the structures of the unknowns in selected chapters, digital versions of all figures, and raw data sets for processing.
This book will stand as a single source to which instructors and students can go to obtain a comprehensive compendium of NMR problems of varying difficulty.

Recenzii

"I like [the book] a lot. Books that cover theory in depth AND lots of problems are (surprisingly) rare." --Steven M. Graham, St. John's University "The abundance of problems and highly detailed glossary are especially noteworthy; the quality of the spectrum presentations is excellent [...] Overall organization works well, and the layout and other 'production values' are what one has long come to expect from [Academic Press]." --Barry Shapiro
"When trying to explain two-dimensional nuclear magnetic resonance (NMR) spectroscopy, one may strive to avoid two pitfalls: getting bogged down in the mathematics behind the technique, or skipping the mathematics altogether and by default making the technique a "magic box." In his book, Simpson (MIT) has nearly done the impossible, covering two-dimensional NMR without slipping into either of those problems. Starting off with the instrumental setups and working through topics such as pulse sequences and spectral interpretation, this book gives readers all that they will need to prepare, run, and interpret a 2-D NMR experiment. This work would be useful for anyone who is currently using 2-D NMR and is a must for newcomers to the technique. Simpson provides almost 100 spectra to interpret as exercises, which make this volume an ideal teaching tool for 2-D NMR spectroscopy. Summing Up: Essential. Upper-division undergraduate through professional collections." -- S. S. Mason, Mount Union College writing CHOICE April 2009
"This book achieves what it sets out in its title. It is a balanced text covering both theoretical and practical aspects of NMR spectroscopy. The first seven chapters give a comprehensive discussion of the relevant theories and practical considerations in the use of NMR spectroscopy for organic structure determination. The later chapters delve into strategies for organic structure determination and provide complex and simple assignment and identification problems, representing the most common applications of 2D NMR… I found this book to be very well written and accessible." --Chemistry World
