If you are looking for MS, IR and NMR practice questions for your introductory organic chemistry class, then this is the book for you. Every problem has a solution with all of the key peaks assigned so that if you miss a question you will be able to see what you may have missed and hopefully improve when you answer related questions in your class. There are several practice problem types to help you. First, there are questions with only one type of technique: mass spectrometry only, infrared spectroscopy only, or nuclear magnetic resonance spectrometry only. Then there is a section where you use two techniques together: mass spectrometry plus infrared spectroscopy or nuclear magnetic resonance spectrometry plus infrared spectroscopy. The examples are chosen to be useful to students in an introductory organic class, a refreshing approach compared to the overly complex examples found in many texts, which are designed for students in more advanced classes.
This book “Concise Organic Spectroscopy-Problems with solutions” illustrates the determination of structures of organic compounds by spectroscopic methods, which are generally incorporated in the syllabi of Indian universities for undergraduate and postgraduate courses. It covers the introductory part of all the spectroscopy techniques with questions and answers. It also describes structure elucidation of organic compounds by spectra like UV, IR, NMR and mass spectral data. This book is advantageous for students of UG, PG and research students.
Though the format evolved in the first edition remains intact, relevant new additions have been inserted at appropriate places in various chapters of the book. Also included are a number of sample and study problems at the end of each chapter to illustrate the approach to problem solving that involve translations of sets of spectra into chemical structures. Written primarily to stimulate the interest of students in spectroscopy and make them aware of the latest developments in this field, this book begins with a general introduction to electromagnetic radiation and molecular spectroscopy. In addition to the usual topics on IR, UV, NMR and Mass spectrometry, it includes substantial material on the currently useful techniques such as FT-IR, FT-NMR 13C-NMR, 2D-NMR, GC/MS, FAB/MS, Tendem and Negative Ion Mass Spectrometry for students engaged in advanced studies. Finally it gives a detailed account on Optical Rotatory Dispersion (ORD) and Circular Dichroism (CD).
A unique textbook, aimed at undergraduate students, containing large numbers of spectra, problems and marginal notes, specifically chosen to highlight the points being discussed.
The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. A critical part of any such course is a suitable set of problems to develop the student’s understanding of how structures are determined from spectra. Organic Structures from Spectra, Fifth Edition is a carefully chosen set of more than 280 structural problems employing the major modern spectroscopic techniques, a selection of 27 problems using 2D-NMR spectroscopy, more than 20 problems specifically dealing with the interpretation of spin-spin coupling in proton NMR spectra and 8 problems based on the quantitative analysis of mixtures using proton and carbon NMR spectroscopy. All of the problems are graded to develop and consolidate the student’s understanding of organic spectroscopy. The accompanying text is descriptive and only explains the underlying theory at a level which is sufficient to tackle the problems. The text includes condensed tables of characteristic spectral properties covering the frequently encountered functional groups. The examples themselves have been selected to include all important common structural features found in organic compounds and to emphasise connectivity arguments. Many of the compounds were synthesised specifically for this purpose. There are many more easy problems, to build confidence and demonstrate basic principles, than in other collections. The fifth edition of this popular textbook: • includes more than 250 new spectra and more than 25 completely new problems; • now incorporates an expanded suite of new problems dealing with the analysis of 2D NMR spectra (COSY, C H Correlation spectroscopy, HMBC, NOESY and TOCSY); • has been expanded and updated to reflect the new developments in NMR and to retire older techniques that are no longer in common use; • provides a set of problems dealing specifically with the quantitative analysis of mixtures using NMR spectroscopy; • features proton NMR spectra obtained at 200, 400 and 600 MHz and 13C NMR spectra include DEPT experiments as well as proton-coupled experiments; • contains 6 problems in the style of the experimental section of a research paper and two examples of fully worked solutions. Organic Structures from Spectra, Fifth Edition will prove invaluable for students of Chemistry, Pharmacy and Biochemistry taking a first course in Organic Chemistry. Contents Preface Introduction Ultraviolet Spectroscopy Infrared Spectroscopy Mass Spectrometry Nuclear Magnetic Resonance Spectroscopy 2DNMR Problems Index Reviews from earlier editions “Your book is becoming one of the “go to” books for teaching structure determination here in the States. Great work!” “…I would definitely state that this book is the most useful aid to basic organic spectroscopy teaching in existence and I would strongly recommend every instructor in this area to use it either as a source of examples or as a class textbook”. Magnetic Resonance in Chemistry “Over the past year I have trained many students using problems in your book - they initially find it as a task. But after doing 3-4 problems with all their brains activities... working out the rest of the problems become a mania. They get addicted to the problem solving and every time they solve a problem by themselves, their confident level also increases.” “I am teaching the fundamentals of Molecular Spectroscopy and your books represent excellent sources of spectroscopic problems for students.”
The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. A critical part of any such course is a suitable set of problems to develop the students’ understanding of how organic structures are determined from spectra. The book builds on the very successful teaching philosophy of learning by hands-on problem solving; carefully graded examples build confidence and develop and consolidate a student’s understanding of organic spectroscopy. Organic Structures from Spectra, 6th Edition is a carefully chosen set of about 250 structural problems employing the major modern spectroscopic techniques, including Mass Spectrometry, 1D and 2D 13C and 1H NMR Spectroscopy and Infrared Spectroscopy. There are 25 problems specifically dealing with the interpretation of spin–spin coupling in proton NMR spectra and 10 problems based on the quantitative analysis of mixtures using proton and carbon NMR spectroscopy. The accompanying text is descriptive and only explains the underlying theory at a level that is sufficient to tackle the problems. The text includes condensed tables of characteristic spectral properties covering the frequently encountered functional groups. The examples themselves have been selected to include all important structural features and to emphasise connectivity arguments and stereochemistry. Many of the compounds were synthesised specifically for this book. In this collection, there are many additional easy problems designed to build confidence and to demonstrate basic principles. The Sixth Edition of this popular textbook: now incorporates many new problems using 2D NMR spectra (C–H Correlation spectroscopy, HMBC, COSY, NOESY and TOCSY); has been expanded and updated to reflect the new developments in NMR spectroscopy; has an additional 40 carefully selected basic problems; provides a set of problems dealing specifically with the quantitative analysis of mixtures using NMR spectroscopy; features proton NMR spectra obtained at 200, 400 and 600 MHz and 13C NMR spectra including routine 2D C–H correlation, HMBC spectra and DEPT spectra; contains a selection of problems in the style of the experimental section of a research paper; includes examples of fully worked solutions in the appendix; has a complete set of solutions available to instructors and teachers from the authors. Organic Structures from Spectra, Sixth Edition will prove invaluable for students of Chemistry, Pharmacy and Biochemistry taking a first course in Organic Chemistry.
First published over 40 years ago, this was the first text on the identification of organic compounds using spectroscopy. This text is now considered to be a classic. This text presents a unified approach to the structure determination of organic compounds based largely on mass spectrometry, infrared (IR) spectroscopy, and multinuclear and multidimensional nuclear magnetic resonance (NMR) spectroscopy. The key strength of this text is the extensive set of practice and real-data problems (in Chapters 7 and 8). Even professional chemists use these spectra as reference data. Spectrometric Identification of Organic Compounds is written by and for organic chemists, and emphasizes the synergistic effect resulting from the interplay of the spectra. This book is characterized by its problem-solving approach with extensive reference charts and tables. The 8th edition of this text maintains its student-friendly writing style - wording throughout has been updated for consistency and to be more reflective of modern usage and methods. Chapter 3 on proton NMR spectroscopy has been overhauled and updated. Also, new information on polymers and phosphorus functional groups has been added to Chapter 2 on IR spectroscopy.
The goal of this book is to show beginning organic students how to interpret modern organic spectra to solve challenging organic structures, using IR, MS, 1H, 13C, DEPT and several 2D variations of NMR (COSY, HSQC/HETCOR and HMBC). Theory and instrumentation are not emphasized, but are sufficiently explained so that students have a basic idea about how each method works. Simulated spectra are used to remove real-life complexities that make structures too difficult for beginners to solve.It is exciting for beginning students to learn how to correctly generate an organic structure from a hodgepodge of lines and numbers. This book will show how to do that. A very specific plan of attack is presented to approach every problem in a step-by-step fashion, including a one page worksheet to summarize and organize the information to help focus their thinking for every "What if...'" question that might arise. Many simple problems are presented to show the mechanical steps of how each method is used to help solve organic structures. More complex problems are designed to be simple enough for beginning students, yet complex enough to require a sustained effort to solve using advanced NMR methods. Real molecules are not used, thereby avoiding the difficulties of overlapping peaks and/or extraneous peaks that should not be there and/or missing peaks that should be there. Students will find a clear path to a correct structure, without encountering real-life frustrations. Most of the common functional group features of organic chemistry are included. Oxygen (alcohols, ethers, esters), nitrogen (amines, amides, nitriles, nitro), halogens and/or sulfur atoms are included at key locations so that chemical shifts are different enough to distinguish each type of proton and carbon in the 1H, 13C, COSY, HETCOR/HSQC and HMBC spectra. This minimizes overlap so that the spectra are easier to interpret for beginning students. It is really the various types of NMR spectra that solve a structure. For the more complex problems, 1H, 13C, DEPT, COSY, HETCOR/HSQC and HMBC are included. An IR chapter is included and a simulated IR is provided in structure problems to provide helpful functional group clues, and details about how alkenes and/or aromatic rings are substituted. In the mass spectrometry chapter, examples of the most common organic monofunctional groups are presented and discussed. However, in complex structure problems, MS is mainly used to provide a molecular weight and indicate the presence of nitrogen, chlorine, bromine and/or sulfur when they are present. These clues can be used to obtain a molecular formula and degrees of unsaturation. Pi bonds can be distinguished from rings using the 13C, which provides a good starting point for solving a structure. Problems range from: shorter structure problems that show how each technique can provide clues to solve a structure; to intermediate level problems that require multiple techniques; to very challenging structure problems that require all of the techniques presented in this book. This workbook will work best for students who are learning basic organic structure determination, and want or need to build on what they are learning to take it to the next level. This can be accomplished in a classroom setting or through self-study by motivated students. If you are an instructor who loves spectroscopy, you might consider trying this approach in one of your course settings to judge for yourself if it works for you and your students. If you are an interested student who can't get enough spectroscopy, just have fun working problems.
