Preface

The determination of structural information from spectroscopic data is an integral part of Organic Chemistry courses at all Universities. At the undergraduate level, the principal aim of such courses is to teach students to solve simple structural problems efficiently by using given data of spectroscopic techniques

This book aims to teach students how to solve the Proton Magnetic Resonance (PMR) Spectroscopy problems when PMR data is given for the organic molecules themselves. Almost all available books, on spectroscopy describe Theory, Instrumentation and all the basic concept regarding spectroscopy. This book confronts the student with the PMR spectroscopy examples by showing how each proton due to its different chemical environment shows different chemical shift value, also how protons coupled with neighboring protons and how it shows the splitting pattern. The PMR spectroscopy problem solving approach is learnt by students from this book who then solved themselves all types of PMR problems in examination by practicing a series of problems in this book.

In this book Theoretical explanation is not given, it emphasizes the understanding of the technique actually used in solving the problems and the concept of identifying structural fragments and the logic needed to produce a structure out of the structural fragments. It is not a conventional text book with detailed text explanation. In short this book understands quickly and giving information about chemical shift value in particular functional groups, coupling constants in aliphatic, aromatic, saturated and unsaturated systems in organic molecules, splitting pattern with neighbouring proton/ protons. Also the book has planned the sequence of problems to demonstrate the use of new organic molecule and to test their understanding of PMR spectroscopy. Each problem is followed by sites of Unsaturation and then structure of the organic molecules with assigned chemical shift value for each proton, its coupling constants and splitting patterns, so that if the student fails to solve a problem then they will understand the problem better. The students have to continuously self-assess through the solving problems from this book themselves by using the PMR data.

The book aims to allow students to solve or read themselves PMR data or PMR spectrum but it shouldn’t mean
