Free sample

This book provides information on the techniques needed to analyze foods in laboratory experiments. All topics covered include information on the basic principles, procedures, advantages, limitations, and applications. This book is ideal for undergraduate courses in food analysis and is also an invaluable reference to professionals in the food industry. General information is provided on regulations, standards, labeling, sampling and data handling as background for chapters on specific methods to determine the chemical composition and characteristics of foods. Large, expanded sections on spectroscopy and chromatography also are included. Other methods and instrumentation such as thermal analysis, ion-selective electrodes, enzymes, and immunoassays are covered from the perspective of their use in the analysis of foods. A website with related teaching materials is accessible to instructors who adopt the textbook.

This text is aimed at people who have some familiarity withhigh-resolution NMR and who wish to deepen their understanding ofhow NMR experiments actually ‘work’. This revised andupdated edition takes the same approach as the highly-acclaimedfirst edition. The text concentrates on the description ofcommonly-used experiments and explains in detail the theory behindhow such experiments work. The quantum mechanical tools needed toanalyse pulse sequences are introduced set by step, but theapproach is relatively informal with the emphasis on obtaining agood understanding of how the experiments actually work. The use oftwo-colour printing and a new larger format improves thereadability of the text. In addition, a number of new topics havebeen introduced: How product operators can be extended to describe experimentsin AX2 and AX3 spin systems, thus making it possible to discuss theimportant APT, INEPT and DEPT experiments often used in carbon-13NMR.Spin system analysis i.e. how shifts and couplings can beextracted from strongly-coupled (second-order) spectra.How the presence of chemically equivalent spins leads tospectral features which are somewhat unusual and possiblymisleading, even at high magnetic fields.A discussion of chemical exchange effects has been introducedin order to help with the explanation of transverserelaxation.The double-quantum spectroscopy of a three-spin system is nowconsidered in more detail.

Reviews of the First Edition

“For anyone wishing to know what really goes on in theirNMR experiments, I would highly recommend this book” –Chemistry World

“…I warmly recommend for budding NMRspectroscopists, or others who wish to deepen their understandingof elementary NMR theory or theoretical tools” –Magnetic Resonance in Chemistry

The derivation of structural information from spectroscopic datais now an integral part of organic chemistry courses at allUniversities.  A critical part of any such course is asuitable set of problems to develop the student’sunderstanding of how structures are determined fromspectra. 

Organic Structures from Spectra, Fifth Edition is acarefully chosen set of more than 280 structural problems employingthe major modern spectroscopic techniques, a selection of 27problems using 2D-NMR spectroscopy, more than 20 problemsspecifically dealing with the interpretation of spin-spin couplingin proton NMR spectra and 8 problems based on the quantitativeanalysis of mixtures using proton and carbon NMRspectroscopy.  All of the problems are graded to develop andconsolidate the student’s understanding of organicspectroscopy.  The accompanying text is descriptive and onlyexplains the underlying theory at a level which is sufficient totackle the problems.  The text includes condensed tables ofcharacteristic spectral properties covering the frequentlyencountered functional groups.

The examples themselves have been selected to include allimportant common structural features found in organic compounds andto emphasise connectivity arguments.  Many of the compoundswere synthesised specifically for this purpose.  There aremany more easy problems, to build confidence and demonstrate basicprinciples, than in other collections. 

The fifth edition of this popular textbook:

• includes more than 250 new spectra and more than 25completely new problems;
• now incorporates an expanded suite of new problemsdealing with the analysis of 2D NMR spectra (COSY, C H Correlationspectroscopy, HMBC, NOESY and TOCSY); 
• has been expanded and updated to reflect the newdevelopments in NMR and to retire older techniques that are nolonger in common use;
• provides a set of problems dealing specifically withthe quantitative analysis of mixtures using NMR spectroscopy;
• features proton NMR spectra obtained at 200, 400 and600 MHz and 13C NMR spectra include DEPT experiments as well asproton-coupled experiments;
• contains 6 problems in the style of the experimentalsection of a research paper and two examples of fully workedsolutions.

Organic Structures from Spectra, Fifth Edition will proveinvaluable for students of Chemistry, Pharmacy and Biochemistrytaking a first course in Organic Chemistry.

Reviews from earlier editions

“Your book is becoming one of the “go to”books for teaching structure determination here in theStates.  Great work!”

“…I would definitely state that this book is themost useful aid to basic organic spectroscopy teaching in existenceand I would strongly recommend every instructor in this area to useit either as a source of examples or as a classtextbook”.
Magnetic Resonance in Chemistry

“Over the past year I have trained many students usingproblems in your book - they initially find it as a task.  Butafter doing 3-4 problems with all their brains activities...working out the rest of the problems become a mania.  They getaddicted to the problem solving and every time they solve a problemby themselves, their confident level also increases.”

 “I am teaching the fundamentals of MolecularSpectroscopy and your books represent excellent sources ofspectroscopic problems for students.”
