Physical Methods in Heterocyclic Chemistry, Volume III provides information pertinent to ionization constants and ultraviolet spectra. This book discusses the methods for the prediction of ionization constants. Comprised of seven chapters, this volume starts with an overview of the ionization constants of a number of heterocyclic compounds. This text then describes the procedures that are usually followed when molecular structure determinations based on electron diffraction measurements are carried out. Other chapters consider the concept of group frequencies, which rests upon the experimental fact that certain groups of atom give rise to vibrational transitions which are close or at the same frequency irrespective of the particular molecule in which the group occurs. The final chapter deals with the optical rotatory power, which is the only generally accessible physical property by which enantiomers can be distinguished in isolation. Heterocyclic chemists, biochemists, molecular biologists, and researchers will find this book extremely useful.

Physical Methods in Heterocyclic Chemistry, Volume VI discusses several topics including bond energies, electron-spin resonance, microwave spectroscopy, and photoelectron spectroscopy. This book explores the thermochemical applications to heterocyclic chemistry. Comprised of five chapters, this volume starts with an overview of the technique of photoelectron spectroscopy. This text then illustrates the various potentialities of photoelectron spectroscopy by discussing four examples taken from the field of heterocyclic compounds. Other chapters determine the magnitudes as well as the lines of action of electric dipole moments in the molecular framework. This book discusses as well the emission of light by individual molecules in solution, particularly heterocyclic molecules, which are electronically excited as a result of the absorption of visible or ultraviolet light. The final chapter deals with the aspects of heats of combustion, heats of hydrogenation, heats of formation, and bond energies. Heterocyclic chemists, chemists, biochemists, molecular biologists, and researchers will find this book extremely useful.

Physical Methods in Heterocyclic Chemistry, Volume V: Handbook of Molecular Dimensions focuses on bond lengths and angles from X-ray crystallography. This book provides a list of known X-ray structure determinations of molecules and ions that contain heterocyclic rings. Comprised of one chapter, this volume starts with an overview of the use of X-ray diffraction for the study of the geometry of molecules of all types. This text then discusses the three primary reasons for the lack of accuracy in bond lengths and angles determined by X-ray diffraction. This book discusses as well the effect of substitution on the bond lengths and angles in a heterocyclic ring system. The reader is also introduced to the various factors influencing the magnitudes of bond lengths and angles in molecules, which include the degree of hybridization, bond orders, electronegativity, interelectronic repulsion, or the equivalent concepts in terms of which these factors may be expressed. Heterocyclic chemists, biochemists, molecular biologists, and researchers will find this book useful.

Physical Methods in Heterocyclic Chemistry, Volume IV, discusses the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry. Since the publication in 1963 of the first two volumes of this treatise, the application of physical methods to organic chemistry, and in particular to heterocyclic chemistry, has proceeded apace. The importance of physical methods to structure determination and to the understanding of inter- and intramolecular interactions has increased no less than the flood of new work. Heterocyclic chemists are thus faced with the necessity of having more to comprehend for the efficient execution of their own work. The present volume includes chapters on electric dipole moments and heteroaromatic reactivity, which originally appeared in Volume I, and chapters on nuclear quadrupole resonance, nuclear magnetic resonance, and infrared spectra, which originally formed part of Volume II. Also included is one new topic: dielectric absorption.

Covering the fundamentals of heterocyclic reactivity and synthesis, this book teaches the subject in a way that is understandable to graduate students. Recognizing the level at which heterocyclic chemistry is often taught, the authors have included advanced material that make it appropriate for postgraduate courses. The text discusses the chemical reactivity and synthesis of particular heterocyclic systems. Exercises and solutions help students understand and apply the principles. Original references are included throughout, as well as many review references.

Provides a one-volume overall picture of the largest of the classical divisions of organic chemistry, suitable for the graduate or advanced undergraduate student, as well as for research workers, both specialists in the field and those engaged in another discipline and requiring knowledge of heterocyclic chemistry. It represents Volume 9 of Comprehensive Heterocyclic Chemistry and utilizes the general chapters which appear in the 8-volume work. The highly systematic coverage given to the subject makes this the most authoritative one-volume account of modern heterocyclic chemistry available.
